A vulnerability was identified in Zackriya-Solutions Meetily up to 0.4.1. Affected is an unknown function of the file backend/app/main.py. The manipulation leads to missing authentication. The attack is possible to be carried out remotely. The exploit is publicly available and might be used. The legacy backend was not removed yet. Vulnerable code is still present on main. The vendor explains: "[W]e are moving towards a single unified application using the tauri framework, and we deprecated the client-server architecture of this application."

A flaw has been found in Cairo-dock Glx-Dock 3.4.0. The affected element is an unknown function of the file bg_forum.php of the component href Attribute Handler. This manipulation of the argument f causes cross site scripting. The attack may be initiated remotely. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Zebra before 7.0.0 contains an inefficient algorithmic complexity vulnerability that allows unauthenticated peers to exhaust verification threads by submitting transactions with many transparent inputs. Attackers can relay invalid transactions with tens of thousands of inputs, forcing quadratic ZIP-244 or ZIP-243 digest recomputation that stalls Rayon-backed block verification for minutes.

Zebra from 2.3.0 before 7.0.0 contains a denial of service vulnerability that allows unauthenticated peers to evade misbehavior scoring by sending transactions or blocks with invalid transparent scripts. Attackers can flood mempool with script-failing transactions or serve forged v5 block bodies with altered scriptSig bytes to exhaust CPU and repeatedly stall block sync.

OpenAM from 14.0.0 before 16.1.4 contains an information disclosure vulnerability that allows unauthenticated attackers to read live session tokens from the notification WebSocket. Attackers can bypass the agent-only check through an unvalidated internal forward on legacy Liberty ID-FF endpoints, collecting iPlanetDirectoryPro tokens to hijack user and administrator sessions.

OpenAM before 16.1.4 contains an open redirect vulnerability that allows attackers to redirect users to external sites because RelayState is unchecked when no relayStateUrlList is configured. Attackers can craft single sign-on links with a malicious RelayState to send users from the trusted OpenAM origin to phishing sites and bypass URL filters.

ZEBRA is a Zcash node written entirely in Rust. Prior to version 4.4.0, Zebra's block validator undercounts transparent signature operations against the 20000-sigop block limit (MAX_BLOCK_SIGOPS), allowing it to accept blocks that zcashd rejects with bad-blk-sigops. A miner who produces such a block can split the network: Zebra nodes follow the offending chain while zcashd nodes do not. This issue has been patched in version 4.4.0.

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, an attacker authenticated to an enabled Zebra RPC endpoint can terminate zebrad by supplying a getblocktemplate LongPollId containing multi-byte UTF-8 characters. In zebra-rpc/src/methods/types/long_poll.rs, LongPollId::from_str originally checked the input byte length and then sliced fixed byte ranges to parse encoded fields. A slice boundary can land inside a multi-byte character and trigger Rust's byte index is not a char boundary panic. Zebra release builds use panic equals abort, so one malformed authenticated RPC request terminates the entire node process and can be repeated after restart. This issue is fixed in version 4.5.0.

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, one unauthenticated P2P peer can monopolize all 25 MAX_INBOUND_CONCURRENCY slots in Zebra's inbound mempool download and verification pipeline. In zebrad/src/components/mempool/downloads.rs, the bounded queue was shared globally without per-peer accounting, while peer identity was not carried through Gossip and FullQueue responses were mapped to Response::Nil instead of reaching overload disconnection handling. An attacker can advertise fake transaction identifiers and remain silent so each task holds a slot until TRANSACTION_DOWNLOAD_TIMEOUT, then periodically refill the queue as slots expire. While saturated, honest peer transactions and local sendrawtransaction requests are rejected with MempoolError::FullQueue, although block validation and synchronization continue. This issue is fixed in version 4.5.0.

ZEBRA is a Zcash node written entirely in Rust. Prior to version 4.4.0, a composite denial-of-service vulnerability in Zebra's block discovery pipeline allows an unauthenticated remote attacker to permanently halt all new block discovery on a targeted node. The attack exploits three independent weaknesses in the gossip, syncer, and download subsystems — all exercisable from a single TCP connection — to create a monotonically growing block deficit that never self-heals. This issue has been patched in version 4.4.0.

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, a natural or attacker-influenced chain fork can leave stale Sapling and Orchard note-commitment subtree roots in Zebra state. In zebra-state/src/service/non_finalized_state/chain.rs, Chain::pop_tip removed a reverted tip block but did not remove subtree entries whose end_height belonged to that block, unlike the cleanup performed by pop_root. When the winning fork later finalized, the abandoned branch's stale subtree data could be written to RocksDB and survive node restarts. The corrupted history can cause z_getsubtreesbyindex consumers such as lightwalletd and light wallets to receive incorrect subtree roots, producing wallet synchronization failures or incorrect wallet state and requiring a full state rebuild for recovery. This issue is fixed in version 4.5.0.

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, an unauthenticated P2P peer can cause the mempool download pipeline to retain transactions after verification reaches the outer RATE_LIMIT_DELAY timeout. In zebrad/src/components/mempool/downloads.rs, Downloads::poll_next removed cancel_handles entries after success and ordinary verification errors, but tokio::time::error::Elapsed did not carry the UnminedTxId needed to remove the timed-out entry. Each retained cancel_handles entry could hold a full Gossip::Tx(UnminedTx), while normal mined-transaction cleanup could not match attacker transactions and no periodic garbage collection or count cap existed. Sustained traffic therefore caused monotonic memory growth until swap pressure degraded the node or the operating system terminated the zebrad process for exhausting memory. This issue is fixed in version 4.5.0.

ZEBRA is a Zcash node written entirely in Rust. Prior to 4.5.0, an unauthenticated IPv4 peer can deterministically terminate a synced Zebra node using the default Linux dual-stack listener configuration. The handshake path canonicalized an IPv4-mapped IPv6 PeerSocketAddr such as ::ffff:127.0.0.1 to plain IPv4 before storing it through MetaAddr::new_connected, but the mempool misbehavior path forwarded the raw transient address to MetaAddrChange::UpdateMisbehavior. In zebra-network/src/meta_addr.rs, apply_to_meta_addr then compared the canonical address-book entry with the raw update address and reached its unexpected address mismatch assertion. After the misbehavior batch flush, panic equals abort terminated zebrad; the peer only needed to complete a P2P handshake and advertise an invalid mempool transaction. This issue is fixed in version 4.5.0.

A flaw was found in Foreman’s Api::V2::SshKeysController, where the target user is resolved through Foreman::Controller::UserAware#find_user using User.find(params[:user_id]) without enforcing the required parent-user authorization check. An attacker with the create_ssh_keys permission can exploit this authorization bypass by submitting POST /api/v2/users/:user_id/ssh_keys with another user’s ID and injecting their own public SSH key into the targeted account. The injected key is subsequently propagated to hosts provisioned by that user, potentially allowing the attacker to authenticate to and gain SSH access to the victim’s managed hosts.

A flaw was found in Foreman’s Api::V2::MailNotificationsController, where authorization checks on user-specific mail-notification resources are insufficient. The GET /api/v2/users/:id/mail_notifications endpoint resolves the target account using User.find(params[:id]) without verifying that the authenticated user is authorized to access that user’s notification configuration. Additionally, the POST and PUT /api/v2/users/:user_id/mail_notifications paths call deny_access when the requester is unauthorized but fail to halt execution, allowing the request to continue and persist the unauthorized change despite a 403 response or subsequent DoubleRenderError. This can allow a user to disclose another user’s mail-notification configuration, including mail_query values, and, where write permissions apply, modify or create notification settings for another user.

A flaw was found in ansible-core's ansible.builtin.git module. The module invokes git (ls-remote, clone, fetch) with the repository URL as a positional argument and without a "--" separator, so a repository URL that begins with a dash is interpreted by git as a command-line option. A caller that passes an attacker-controlled repository URL to the module can trigger argument injection (for example --upload-pack/--exec), resulting in arbitrary command execution on the host running the module.

A flaw was found in Katello where the Content View Filter Rules API does not properly enforce authorization on the parent Content View Filter. An authenticated, low-privileged user with Content View permissions in one organization may be able to access and modify filter rules belonging to a Content View Filter in another organization by supplying that filter's identifier. This can result in unauthorized disclosure of filter-rule information and unauthorized changes to unpublished Content View filter configuration.

A flaw was found in Foreman. The template revision endpoint does not enforce object-level authorization when retrieving an audited template revision. An authenticated, low privileged user with a template-related permission, such as view_ptables, can obtain historical template contents belonging to another organization or location by supplying the corresponding audit ID. This can result in unauthorized disclosure of historical template contents, which may contain sensitive configuration information, credentials, or other secrets. The REST API revision endpoints correctly restrict this lookup.

ClickMigrate is a database migration tool for ClickHouse with automatic SQL migration management and version tracking. Prior to version 1.0.3, a path traversal vulnerability in the revision command allowed a crafted migration name supplied via the -m argument to escape the intended migrations directory. Under specific conditions, an attacker could cause the tool to create a .sql file in an arbitrary location writable by the user executing the command. This issue is only exploitable if an attacker can influence the migration name passed to the revision command, such as through an insecure automation or CI/CD pipeline that forwards untrusted input. This issue has been patched in version 1.0.3.

Algernon is a small self-contained pure-Go web server. Prior to version 1.17.10, Algernon's URL-prefix authorization gate matches its protected prefixes (/admin, /repo, /data) with case-sensitive strings.HasPrefix, while the exact same raw req.URL.Path is later resolved against the filesystem. On case-insensitive filesystems (Windows NTFS — always; macOS APFS/HFS+ — default), a request for /Admin/secret.lua evades every protected-prefix check, falls through to the public-prefix accept branch, and then resolves on disk to admin/secret.lua. The result is an unauthenticated bypass of the /admin, /repo, and /data authorization boundary, enabling read (and, for Lua files, execution) of protected content. The permission system is active in the default configuration. This issue has been patched in version 1.17.10.

Paaster is a pastebin application. Prior to version 3.3.0, Paaster's account login has no rate limiting, lockout, or CAPTCHA of any kind, and a companion endpoint openly discloses whether a username exists along with that account's password-hashing salts. Together these let an attacker enumerate real accounts and then brute-force their passwords with unlimited, unthrottled attempts. This issue has been patched in version 3.3.0.

taOS is a self-hosted AI agent OS. Prior to version 1.0.0-beta.23, the POST /api/skill-exec/{skill_id}/call endpoint in taOS executes built-in skills — including the code_exec skill which runs arbitrary Python via subprocess.run(["python3", "-c", code]) — without performing any admin role check, skill ownership check, or agent assignment verification. Any authenticated non-admin user can supply attacker-controlled Python code in the request body and have it executed as the taOS backend process user on the host, achieving full remote code execution with no privilege escalation required beyond a valid (non-admin) session. This issue has been patched in version 1.0.0-beta.23.

Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.71, Heym's workflow engine accepts an arbitrary Python code string in the playwrightCode field of a Playwright node. This string is written to a temporary .py file and executed directly by the backend process via subprocess.Popen([sys.executable, script_path]) with no sandboxing, AST validation, or role gate. Any authenticated user — including a freshly registered account — can achieve full remote code execution (RCE) on the backend host, running as the service process user (observed as root in the default Docker deployment). This issue has been patched in version 0.0.71.

Heym builds and runs agentic systems and business-process automations on self-hosted infrastructure. Prior to version 0.0.70, get_workflow_template / get_node_template fetches a template by ID with no visibility / author / shared_with predicate, so any authenticated user can read (and use) any other tenant's private (visibility=specific_users) template — including its full node/edge graph and the email addresses it was shared with. The list endpoint enforces visibility correctly; the single-item get/use paths do not. This issue has been patched in version 0.0.70.

ideon is a self-hosted visual workspace. Prior to version 0.9.4, validateUrlForSSRF() / safeFetch() in lib/oauth/ssrf-protection.ts (and the parallel validateMcpUrl() in lib/security/validators.ts) perform SSRF host-blocking by string/regex matching on new URL(url).hostname. Their IPv6 branch only recognises the textual forms ::1, fe80:/fc00:/fd00: prefixes, and the dotted-decimal IPv4-mapped form ::ffff:127.x. It does not recognise the WHATWG-canonical IPv4-mapped-IPv6 host that Node emits for a mapped address, which is hex-compressed and bracket-wrapped: [::ffff:7f00:1] for 127.0.0.1, [::ffff:a9fe:a9fe] for 169.254.169.254. An authenticated user who registers a STREAMABLE_HTTP / SSE MCP server with URL http://[::ffff:7f00:1]:PORT/ (loopback) or http://[::ffff:a9fe:a9fe]/ (cloud metadata) passes both guards, and the server-side OAuth-discovery action then fetches that host, yielding server-side request forgery to loopback and to the cloud metadata service. This issue has been patched in version 0.9.4.

BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.4, 1.5.1, and 1.6.0, the current master demo server can be crashed remotely over BACnet/IP by sending a valid Confirmed WriteProperty request that updates loop-1's controlled-variable-reference to point to life-safety-zone-1 / accepted-modes. This issue has been patched in versions 1.4.4, 1.5.1, and 1.6.0.

BACnet Stack is a BACnet open source protocol stack C library for embedded systems. In versions 1.5.0 and 1.6.0-rc1, there is a restore logic flaw in bacnet-stack that is reachable through the official, unmodified apps/server management path when BACNET_BACKUP_RESTORE is enabled. This issue has been patched in versions 1.5.1 and 1.6.0.

BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.4 and 1.5.1, an out-of-bounds read vulnerability exists in bacnet-stack's AtomicWriteFile record-access path. The bug is caused by a mismatch between an externally controlled returnedRecordCount field and the fixed-size internal fileData[] array used by BACNET_ATOMIC_WRITE_FILE_DATA. This issue has been patched in versions 1.4.4 and 1.5.1.

split_image_check() in boot/bootutil/src/loader.c declares a fixed uint8_t loader_hash[32] buffer and passes it as the out_hash out-parameter to bootutil_img_validate(). That routine copies IMAGE_HASH_SIZE bytes into out_hash (memcpy(out_hash, hash, IMAGE_HASH_SIZE) in boot/bootutil/src/image_validate.c), where IMAGE_HASH_SIZE is a compile-time constant of 64 for MCUBOOT_SHA512 or 48 for MCUBOOT_SIGN_EC384/SHA-384 (boot/bootutil/include/bootutil/crypto/sha.h). The buffer tracks SHA-256 (32 bytes) while the copy length tracks the configured algorithm, so the write overruns the buffer by 16 or 32 bytes. The overflow is only present in a non-default configuration: the legacy Mynewt split-image feature must be compiled (split_go()/split_image_check(), i.e. neither MCUBOOT_DIRECT_XIP nor MCUBOOT_RAM_LOAD), the digest must be larger than 32 bytes (MCUBOOT_SHA512 or MCUBOOT_SIGN_EC384), and MCUBOOT_SIGN_PURE must be off. split_go() is a public API with no caller inside MCUboot; it is invoked from a Mynewt application. In the default SHA-256 build there is no overflow. The over-written bytes are the one-way digest of the loader image and the overflow length is fixed at build time, so the contents are not meaningfully attacker-controlled and the size is not attacker-chosen. The realistic impact is bounded, uncontrolled corruption of the bootloader's stack on the split-boot path, manifesting as instability or failed boot in the affected configuration rather than reliable code execution. The fix is to size loader_hash to IMAGE_HASH_SIZE and pass IMAGE_HASH_SIZE as the matching seed length.

MCUboot's Zephyr serial-recovery upload handler bs_upload() in boot/boot_serial/src/boot_serial.c decodes the host-supplied image field of an MCUmgr image-upload request into img_num (a full 32-bit value) and latches it on the off == 0 packet without any range check. It then passes img_num straight to flash_area_id_from_multi_image_slot(img_num, 0), which on the Zephyr port resolves to __flash_area_ids_for_slot() in boot/zephyr/include/sysflash/sysflash.h and indexes the static const int all_slots[] table as all_slots[img_num 2]. That table holds only MCUBOOT_IMAGE_NUMBER 2 entries, so any img_num >= MCUBOOT_IMAGE_NUMBER is an out-of-bounds read. The path is reachable by anyone with access to the serial / SMP recovery console, which is unauthenticated by design, and the bad value is supplied before any image signature is verified. The defect is specific to the default non-direct upload path (MCUBOOT_SERIAL_DIRECT_IMAGE_UPLOAD disabled) on the Zephyr port with the array-backed slot layout (not CONFIG_SINGLE_APPLICATION_SLOT). It is not gated on a multi-image configuration: MCUBOOT_IMAGE_NUMBER defaults to 1, so even a default single-image build is affected for any image >= 1. The MCUBOOT_SERIAL_DIRECT_IMAGE_UPLOAD path is safe (its flash_area_id_from_direct_image() switch returns -EINVAL for unknown indices). flash_area_id_from_multi_image_slot() takes a signed int image_index while img_num is uint32_t, so the attacker controls the sign of the index as well as its magnitude: an image of 0xFFFFFFFF converts to -1 and reads all_slots[-2], off the front of the table, while large positive values read off the end (CWE-192). Either way the index multiply img * 2 is performed in int, so a wild offset yields a bus/hard fault, giving a reliable denial of service of the bootloader during recovery. For moderately out-of-range indices the read returns adjacent .rodata as a garbage flash-area id that is handed to flash_area_open(); this normally fails with MGMT_ERR_EINVAL, but if the garbage id happens to match a valid non-image partition, the subsequent erase/write can target a partition outside the image set (CWE-787). The attacker-supplied value is never echoed back, so there is no information disclosure. The fix is to reject img_num >= BOOT_IMAGE_NUMBER on the off == 0 packet, before the slot lookup. The comparison must be made on the unsigned img_num: an equivalent guard applied after the conversion to int would not reject the negative case above. __flash_area_ids_for_slot() should bounds-check its own arguments as defence in depth. This vulnerability was reported independently twice: by NVIDIA Project Vanessa on 2026-06-22, and by Kai Phan (@kaimandalic) on 2026-07-19 as GHSA-8v33-88p6-jffj, which is closed as a duplicate of this advisory. Both original reports are reproduced in full below.

boot_save_boot_status() in boot/bootutil/src/boot_record.c reads the image's EXPECTED_HASH_TLV into a stack buffer image_hash[IMAGE_HASH_SIZE] that is never zero-initialised. The TLV handler validates only the upper bound (len > sizeof(image_hash)) and then reads exactly len bytes, so a TLV shorter than IMAGE_HASH_SIZE leaves the tail of image_hash holding stale stack content. The subsequent copy into the boot record, memcpy(buf + offset, image_hash, sizeof(image_hash)), uses the fixed buffer size rather than len, so up to IMAGE_HASH_SIZE - 1 bytes of uninitialised bootloader stack are written into the measured-boot record. The defect is reachable only under MCUBOOT_MEASURED_BOOT, and only when the image reaching boot_save_boot_status() was not hash-validated on that boot. bootutil_img_validate() rejects a hash TLV whose length is not exactly sizeof(hash) (boot/bootutil/src/image_validate.c:345), and primary-slot validation is on by default (Zephyr's CONFIG_BOOT_VALIDATE_SLOT0 defaults to y), so in a default build the malformed image never reaches this code. The direct-XIP and RAM-load strategies in boot/bootutil/src/loader.c validate the selected slot unconditionally and are not affected. The short TLV survives only where the integrator has turned primary-slot validation off: the swap and overwrite loader built without MCUBOOT_VALIDATE_PRIMARY_SLOT, which checks only the image magic before calling boot_add_shared_data(), and the Zephyr single-slot loader (boot/zephyr/single_loader.c) built without it, including the MCUBOOT_VALIDATE_PRIMARY_SLOT_ONCE variant, which skips validation once the trailer records an earlier successful one. It is also reachable through a time-of-check/time-of-use change to tamperable external flash between validation and the boot-record read. Placing the crafted image requires physical or flash-write access to the device; in a single-slot build with serial recovery enabled, the serial-recovery upload writes the primary slot directly and can place it as well. In these configurations the boot record's measurement is already not trustworthy: with validation off, the hash copied into the record is the image's own unverified EXPECTED_HASH_TLV, which the attacker chooses. The defect therefore does not weaken attestation integrity any further. What it adds is a path for bootloader memory to leave the device: up to 63 bytes (IMAGE_HASH_SIZE - 1) of uninitialised bootloader stack are embedded in the measurement field that a downstream attestation service sends to a remote verifier. In the configurations analysed the residue is bootloader internal state (TLV offsets and lengths, flash addresses, loop state), not key material, but what occupies that stack region depends on configuration and on which code ran before boot_save_boot_status(). It is reported as a low-severity, defense-in-depth disclosure with no integrity or availability impact. This is distinct from the already-fixed record_len integer underflow in the same routine (GHSA-8hrv-4cp5-4rg3). The fix rejects any EXPECTED_HASH_TLV whose length is not exactly IMAGE_HASH_SIZE.

MCUboot's serial-recovery image-upload handler bs_upload() in boot/boot_serial/src/boot_serial.c declares const struct flash_area *fap = NULL and assigns it only via flash_area_open() part-way through the function. Two early validation failures (goto out_invalid_data) — a CBOR map that fails to decode, or an upload packet missing the off/data members — branch past the open while fap is still NULL, then fall into the shared epilogue. In MCUBOOT_ENC_IMAGES builds that epilogue unconditionally calls boot_handle_enc_fw(fap), which reaches boot_image_load_header() and flash_area_read() and dereferences the NULL flash_area. The defect is reachable pre-authentication: the trigger is the very first serial-recovery upload command carrying a malformed payload. The guarding conditions are default-true on a fresh recovery session — img_num, curr_off and img_size are zero-initialized statics, so curr_off == img_size and the primary-slot test both hold. It requires a non-default build: encrypted images (MCUBOOT_ENC_IMAGES / Zephyr CONFIG_BOOT_ENCRYPT_IMAGE) together with an active serial-recovery transport, on the Zephyr or Mynewt port (the two that build both boot/boot_serial/src/boot_serial.c and boot_serial_encryption.c with MCUBOOT_ENC_IMAGES). The impact is a transient denial of service of the bootloader during recovery. fap is a hard NULL rather than an attacker-controlled value, so there is no memory-corruption or information-leak primitive and image authentication is unaffected. Whether the dereference faults is platform-dependent — on targets where address 0x0 is mapped readable flash the read merely returns an error and execution continues, while targets that trap NULL (MPU / null-pointer-exception detection) take a hard fault. Because serial recovery is unauthenticated by design and already permits the console attacker to write the secondary slot, the added capability is only a low-value transient crash. The related unconditional flash_area_close(fap) call in the same epilogue is a safe no-op on the ports that reach it, so it does not contribute to the dereference. The affected ports are the Zephyr port — boot/zephyr/CMakeLists.txt compiles boot_serial.c under CONFIG_MCUBOOT_SERIAL and boot_serial_encryption.c under CONFIG_BOOT_ENCRYPT_IMAGE — and the Mynewt port, whose mcuboot_config.h defines MCUBOOT_SERIAL unconditionally and MCUBOOT_ENC_IMAGES under any BOOTUTIL_ENCRYPT_ syscfg, with boot/boot_serial/pkg.yml declaring no explicit source list so the whole directory is built. The Espressif port is not affected**: it compiles boot_serial.c but not boot_serial_encryption.c, and defines no MCUBOOT_ENC_IMAGES, so the #ifdef MCUBOOT_ENC_IMAGES block containing the call is preprocessed away. The NuttX, Cypress and Mbed ports do not build boot_serial.c at all.

The VibeBP plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 1.9.9.8.1. This is due to the plugin allowing arbitrary user meta updates through the set_email_notification_settings() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to grant themselves administrator privileges by updating their own 'wp_capabilities' user meta value.

Software installed and run as a non-privileged user may conduct improper GPU system calls through the DDK kernel module interface. Under unsupported use of the interface, a use-after-free condition may occur that can lead to kernel memory corruption, platform instability, or system reboot. The weakness occurs when software references memory after it has been released. Accessing memory after free may result in corruption of valid data structures, unexpected program behaviour, process crashes, or execution of unintended operations.

Tight JPEG decoding in TightVNC and UltraVNC viewers contains a heap-based buffer overflow because an attacker-controlled framebuffer rectangle width is not validated against a fixed-size decoding buffer. A malicious VNC server can cause an out-of-bounds heap write when a user connects, resulting in application crash and potentially other memory-corruption impacts.

When MCUboot is built with the TinyCrypt crypto backend (MCUBOOT_USE_TINYCRYPT), bootutil_aes_ctr_drop() in boot/bootutil/include/bootutil/crypto/aes_ctr_tinycrypt.h was an empty stub. The AES-CTR context for this backend is the fully expanded AES-128 key schedule (struct tc_aes_key_sched_struct). Generic code relies on this hook to release and clear key state, so with TinyCrypt nothing was cleared. The mbedTLS and PSA backends do free or destroy their key state here. As a result, boot_state_clear(), which boot_go() calls before handing off to the application, left the image's AES content-encryption key schedule in the static boot_data state. This is the case after an encrypted upgrade in single-image builds, where boot_enc_zeroize() is not called. boot_decrypt_key() likewise left the ECIES-derived key-encryption key schedule on the stack. The affected build uses MCUBOOT_ENC_IMAGES with TinyCrypt, which is the default ECDSA and Ed25519 backend in the Zephyr port. The first AES-128 round key equals the cipher key, so anyone who can read the leftover bootloader RAM after boot can recover the image content key and decrypt that encrypted image. That includes a physical attacker with debug or RAM access, or code later running on the device. This weakens image-encryption key confidentiality (and so the confidentiality of the encrypted image's plaintext). The device's long-term private decryption key is not exposed, and image authenticity is not affected. The fix wipes the context with bootutil_wipe_memory().

@grpc/grpc-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. From 1.14.0 through 1.14.1, XdsServer in @grpc/grpc-js-xds can acknowledge Route and VirtualHost resources while failing to apply their RBACPerRoute override configurations. The override parser is not registered under the override message type, override maps are stored under a type URL instead of the configured HTTP filter name, and VirtualHost override maps are not read. When experimental RBAC is enabled and a trusted xDS control plane supplies a broad top-level ALLOW policy with a stricter matching override, affected servers evaluate RPCs under the broad policy and can accept requests that should be denied. This issue is fixed in version 1.14.2.

In MCUboot's serial-recovery encrypted-image support (boot/boot_serial/src/boot_serial_encryption.c), decrypt_image_inplace() and boot_image_validate_encrypted() each keep a stack-local struct boot_status. boot_enc_load() writes the plaintext per-image AES key into its enckey[] field. Neither function cleared this structure before returning. In addition, a decrypt failure inside the per-sector loop of decrypt_image_inplace() returned early and skipped the total_out: cleanup, which left the expanded AES key context (enc_data) on the stack as well. The error paths of boot_image_validate_encrypted() similarly skipped boot_enc_zeroize(). The affected code is built when encrypted images (MCUBOOT_ENC_IMAGES, Zephyr CONFIG_BOOT_ENCRYPT_IMAGE) are combined with serial recovery. It runs when an encrypted image is uploaded to the primary slot over the recovery protocol, and when the image list or state is queried while an encrypted image is in the secondary slot. After these functions return, the image's AES content key remains in dead stack memory. An attacker who can later read device RAM, for example through a debug port or retained RAM, can recover it. This weakens the confidentiality of image-encryption keys within the bootloader trust boundary. A recovered key exposes the plaintext of the encrypted firmware image it protects. The device's long-term private decryption key is not exposed. No remote or recovery-protocol channel that returns this memory is known, so exploitation requires a separate memory-read capability.

bootutil_img_hash() computes the image digest over ih_hdr_size + ih_img_size + ih_protect_tlv_size bytes, all three taken from the candidate image's header, and reads that span out of the slot without checking that it fits in the flash area. The three sizes are also summed without an overflow check. Nothing earlier on the validation path bounds the whole span either: bootutil_img_validate() compares the image size against bootutil_max_image_size() only after the hash has been computed. The callers bound part of the span, or none of it: On the swap and overwrite upgrade path, boot_validate_slot() first runs the image header check (boot_is_header_valid(), later boot_check_header_valid()). Before MCUboot 2.2.0 that check covered only ih_hdr_size + ih_img_size, so for every image the protected-TLV area (ih_protect_tlv_size, a uint16_t, up to 65535 bytes) was hashed without being bounded. From 2.2.0 the check includes ih_protect_tlv_size, except for a compressed image in the secondary slot when MCUBOOT_DECOMPRESS_IMAGES (CONFIG_BOOT_DECOMPRESSION) is enabled, which leaves the same gap of up to 64 KB. The serial recovery image-list and image-state handlers (bs_list() and bs_set() in boot/boot_serial/src/boot_serial.c) and Zephyr's single-slot and firmware loaders (boot/zephyr/single_loader.c, boot/zephyr/firmware_loader.c) call bootutil_img_validate() with no header check at all, so on those paths ih_img_size is unbounded as well. The image is hashed before its signature is checked, so anyone who can place an image in a slot (an OTA or SMP update delivered through the application, or serial recovery) reaches this read before authentication. Whether a malformed header produces an actual read beyond the area depends on the flash backend: Backends whose flash_area_read() bounds-checks the request (Zephyr, Espressif, NuttX, Mbed) return an error once the chunked read crosses the end of the area. Validation fails and the image is rejected, with no over-read. With MCUBOOT_HASH_STORAGE_DIRECTLY (Zephyr CONFIG_BOOT_IMG_HASH_DIRECTLY_ON_STORAGE, available from 2.2.0, not enabled by default) the span is hashed through a single direct pointer into memory-mapped flash, with no bounds check. The Cypress PSoC6 port's flash_area_read() (boot/cypress/cy_flash_pal/cy_flash_map.c, from 1.6.0) does not bound the read: its assert()s compare against the area's absolute offset rather than its size, and it copies with memcpy(). The bytes read past the area feed only the digest, which is compared internally and never returned, so nothing is disclosed. The realistic effect is a read fault during image validation: up to 64 KB past the slot on the upgrade path, and potentially much further on the paths that skip the header check. Where validation is repeated at every boot (a pending upgrade, or the single-slot loader checking its image), the fault can recur on each reset and keep the device from booting. The fix makes bootutil_img_hash() add the three sizes with boot_u32_safe_add() and reject an image whose span, including the sector offset used in swap-using-offset mode, does not fit in the flash area, before any of it is hashed. Because the bound is applied where the bytes are read, it covers every caller.
