high Nessus Plugin ID 350846

Language:

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 a vulnerability as referenced in the 15e880b4-b9ed-11f1-b17e-3c7c3fba4204 advisory.

Fetchmail reports:
[CVE-2026-94184]: Fetchmail's NTLM authentication client can in some cases be susceptible to a remote code execution from a malicious server when fetchmail is configured with the NTLM feature enabled, depending on build details. fetchmail 6.6.7 release candidates, 6.6.7 and subsequent releases are unaffected.

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

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

Solution

Update the affected packages.
