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.
