Details

Updated opal 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.

Open Phone Abstraction Library (opal) is implementation of various
telephony and video communication protocols for use over packet based
networks.

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

A flaw was discovered in the way opal handled certain Session Initiation
Protocol (SIP) packets. An attacker could use this flaw to crash an
application, such as Ekiga, which is linked with opal. (CVE-2007-4924)

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