Synopsis

The remote FreeBSD host is missing a security-related update.

Description

SecurityFocus reports :

GnuTLS is prone to a security-bypass vulnerability because the application fails to properly validate chained X.509 certificates.
Successfully exploiting this issue allows attackers to perform man-in-the-middle attacks by impersonating trusted servers.
Unsuspecting users may be under a false sense of security that can aid attackers in launching further attacks.

Solution

Update the affected package.
