FreeBSD : Apache-SSL optional client certificate vulnerability (7557a2b1-5d63-11d8-80e3-0020ed76ef5a)

This script is Copyright (C) 2009-2013 Tenable Network Security, Inc.

Synopsis :

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

Description :

From the Apache-SSL security advisory :

If configured with SSLVerifyClient set to 1 or 3 (client certificates
optional) and SSLFakeBasicAuth, Apache-SSL 1.3.28+1.52 and all earlier
versions would permit a client to use real basic authentication to
forge a client certificate.

All the attacker needed is the 'one-line DN' of a valid user, as used
by faked basic auth in Apache-SSL, and the fixed password ('password'
by default).
