"managed-keys" is a feature which allows a BIND resolver to automatically maintain the keys used by trust anchors which operators configure for use in DNSSEC validation. Due to an error in the managed-keys feature it is possible for a BIND server which uses managed-keys to exit due to an assertion failure if, during key rollover, a trust anchor's keys are replaced with keys which use an unsupported algorithm. Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.5-P1, 9.12.0 -> 9.12.3-P1, and versions 9.9.3-S1 -> 9.11.5-S3 of BIND 9 Supported Preview Edition. Versions 9.13.0 -> 9.13.6 of the 9.13 development branch are also affected. Versions prior to BIND 9.9.0 have not been evaluated for vulnerability to CVE-2018-5745.

"managed-keys" es una característica que permite a un solucionador BIND mantener automáticamente las claves usadas por los anclajes de confianza que los operadores configuran para su uso en la comprobación de DNSSEC. Debido a un error en la funcionalidad managed-keys, es posible que un servidor BIND que utiliza managed-keys salga debido a un error de aserción si, durante la renovación de claves, las claves de un ancla de confianza son reemplazadas por claves que utilizan un algoritmo no compatible. Versiones afectadas: BIND 9.9.0 hasta 9.10.8-P1, 9.11.0 hasta 9.11.5-P1, 9.12.0 hasta 9.12.3-P1 y versiones 9.9.3-S1 hasta 9.11.5- S3 de BIND 9 Supported Preview Edition. Las versiones 9.13.0 hasta 9.13.6 de la rama de desarrollo 9.13 también están afectadas. Las versiones anteriores a BIND 9.9.0 no han sido evaluadas para la vulnerabilidad de CVE-2018-5745.
