Description

Updated pwlib packages that fix a security issue are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

PWLib is a library used to support cross-platform applications.

In Red Hat Enterprise Linux 5, the Ekiga teleconferencing application uses PWLib.

A memory management flaw was discovered in PWLib. An attacker could use this flaw to crash an application, such as Ekiga, which is linked with pwlib (CVE-2007-4897).

Users should upgrade to these updated packages which contain a backported patch to correct this issue.
