supported and is potentially affected by a denial of service
vulnerability as well as other unacknowledged security issues. As of
July 30, 2012, the vendor no longer provides security fixes for the
installed product.

Lack of support implies that no new security patches for the product
will be released by the vendor. As a result, it is likely to contain
security vulnerabilities.");
