DESCRIPTION:
A vulnerability has been reported in Perforce Web Client (P4Web),
which can be exploited by malicious people to cause a DoS (Denial of
Service).

The vulnerability is caused due to an error in the P4Web daemon
(P4Webs.exe) when processing HTTP requests with a "Content-Length"
header greater than 0 with no body. This can be exploited to cause
the process to consume large amounts of CPU resources via a specially
crafted HTTP request.

The vulnerability affects versions 2006.2 and prior.
