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 06bf834f-c31f-11f1-9b94-901b0e13f1a0 advisory.

X.Org reports:
