An issue was discovered in the libsecp256k1 crate before 0.3.1 for Rust. Scalar::check_overflow allows a timing side-channel attack; consequently, attackers can obtain sensitive information.

Versions of `libsecp256k1` prior to `0.3.1` did not execute Scalar::check_overflow in constant time. This allows an attacker to potentially leak information via a timing attack. The flaw was corrected by modifying Scalar::check_overflow to execute in constant time.
