Echo: gnutls28: security update to 3.8.9-3+e8

high Tenable Cloud Security Plugin ID 455148

Description

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

 - A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly
 ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker
 could exploit this to bypass critical name constraint checks during certificate validation. This bypass
 could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle
 attacks against affected systems. (CVE-2026-42011)

Solution

Update the gnutls28 library and its related packages to version 3.8.9-3+e8 or later.
