Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

Jan Lieskovsky reports :

OpenLDAP does not properly handle a '\0' character in a domain name in
the subject's Common Name (CN) field of an X.509 certificate, which
allows man-in-the-middle attackers to spoof arbitrary SSL servers via
a crafted certificate issued by a legitimate Certification Authority
