"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.

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."
