PWLib is a cross-platform class library designed to support the OpenH323
project. OpenH323 provides an implementation of the ITU H.323
teleconferencing protocol, used by packages such as Gnome Meeting.

A test suite for the H.225 protocol (part of the H.323 family) provided by
the NISCC uncovered bugs in PWLib prior to version 1.6.0. An attacker
could trigger these bugs by sending carefully crafted messages to an
application. The effects of such an attack can vary depending on the
application, but would usually result in a Denial of Service. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0097 to this issue.

Users are advised to upgrade to the erratum packages, which contain
backported security fixes and are not vulnerable to these issues.

Red Hat would like to thank Craig Southeren of the OpenH323 project for
providing the fixes for these issues.
