Disclosure Date


Symantec Raptor Firewall contains a flaw that may allow a remote denial of service. The issue is triggered when the firewall tries to parse a "benign" option (such as the Timestamp or Security options) and does not check to see if it is of zero length. If encountered, the firewall will fall into an infinite loop and lock up.
