medium Tenable Self-Hosted Container Security Plugin ID 458539

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)

Solution

Update the gnutls28 library and its related packages to version 3.8.9-3+e4 or later.
