high Nessus Plugin ID 346774

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the gnutls packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier (URI) or Service (SRV) Subject Alternative Names (SANs). This could cause the certificate validation process to incorrectly fall back to checking DNS hostnames against the Common Name (CN), potentially allowing the attacker to spoof legitimate services or intercept sensitive information.(CVE-2026-42012)

Tenable has extracted the preceding description block directly from the EulerOS gnutls security advisory.

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