Fedora: 1.5.0-4 pwlib Denial of Service Moderate Advisory

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 update 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.
