CentOS 9 : gnutls-3.8.10-3.el9

medium Nessus Plugin ID 299202

Synopsis

The remote CentOS host is missing one or more security updates for gnutls.

Description

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the gnutls-3.8.10-3.el9 build changelog.

 - A flaw was found in GnuTLS. This vulnerability allows a denial of service (DoS) by excessive CPU (Central Processing Unit) and memory consumption via specially crafted malicious certificates containing a large number of name constraints and subject alternative names (SANs). (CVE-2025-14831)

 - A flaw was found in the GnuTLS library, specifically in the gnutls_pkcs11_token_init() function that handles PKCS#11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error can cause the application using GnuTLS to crash or, in certain conditions, be exploited for code execution. As a result, systems or applications relying on GnuTLS may be vulnerable to a denial of service or local privilege escalation attacks. (CVE-2025-9820)

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 CentOS 9 Stream gnutls package.
