Critical Update for Red Hat Enterprise Linux: LibreOffice Buffer Overflow

red hat
Calendar Grey August 1, 2012
Scroller Redhat
Crucial patch release for LibreOffice tackles significant vulnerabilities in Red Hat Enterprise Linux 6, enhancing user safety.
Updated libreoffice packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6

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

Summary

LibreOffice is an open source, community-developed office productivity suite. It includes the key desktop applications, such as a word processor, spreadsheet application, presentation manager, formula editor, and a drawing program.
Multiple heap-based buffer overflow flaws were found in the way LibreOffice processed encryption information in the manifest files of OpenDocument Format files. An attacker could provide a specially-crafted OpenDocument Format file that, when opened in a LibreOffice application, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2012-2665)
Upstream acknowledges Timo Warns as the original reporter of these issues.
All LibreOffice users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. All running instances of LibreOffice applications must be restarted for this update to take effect.
