Rocky Linux 9 : gnutls (RLSA-2024:2570)

medium Nessus Plugin ID 196952

Synopsis

The remote Rocky Linux host is missing one or more security updates.

Description

The remote Rocky Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2024:2570 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)

 - A flaw has been discovered in GnuTLS where an application crash can be induced when attempting to verify a specially crafted .pem bundle using the certtool --verify-chain command. (CVE-2024-28835)

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

Solution

Update the affected packages.
