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 fbf59c13-ca23-11f1-ada1-ac5afc632ba3 advisory.

X.Org reports:
Multiple issues have been found in the X client library implementations published by X.Org for which we are releasing security fixes for.

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