Description


Cisco has acknowledged a vulnerability in Cisco PIX and ASA appliances, which can be exploited by malicious people to cause a DoS (Denial of Service).

Successful exploitation requires that the Time-To-Live (TTL) decrement feature is enabled (disabled by default).

The vulnerability affects software versions 7.2(2) and later, prior to 7.2(3)006 or 8.0(3).
