Synopsis

The remote AlmaLinux host is missing a security update.

Description

The remote AlmaLinux 8 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2024:1784 advisory.

 - 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. (CVE-2024-28834)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
