Security Fix

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.
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.
