1. Summary:

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

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
RHEL Optional Productivity Applications (v. 5 server) - i386, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

libwpd is a library for reading and converting Corel WordPerfect Office
documents.

A buffer overflow flaw was found in the way libwpd processed certain
Corel WordPerfect Office documents (.wpd files). An attacker could provide
a specially-crafted .wpd file that, when opened in an application linked
against libwpd, such as OpenOffice.org, would cause the application to
crash or, potentially, execute arbitrary code with the privileges of the
user running the application. (CVE-2012-2149)

All libwpd users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. All running applications
that are linked against libwpd must be restarted for this update to take
effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258
