NVD Description

Note: Versions mentioned in the description apply only to the upstream libgnutls-devel package and not the libgnutls-devel package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in nonce size from 513 to 512 bits, exposing a potential timing side-channel.
