Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the a7b4cdfc-9f9d-11f1-a655-3497f65b111b advisory.

The mod_gnutls project reports:
Security fix (CVE-2026-33307): Fix out-of-bounds write when receiving a client certificate chain longer than the buffer.
Security fix (CVE-2026-33308): Check Key Purpose during client certificate verification.

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

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.
