OpenOffice.org is an office productivity suite that includes desktop applications, such as a word processor, spreadsheet, presentation manager, formula editor, and a drawing program. An integer underflow flaw and a boundary error flaw, both possibly leading to a heap-based buffer overflow, were found in the way OpenOffice.org parses certain records in Microsoft Word documents. An attacker could create a specially-crafted Microsoft Word document, which once opened by an unsuspecting user, could cause OpenOffice.org to crash or, potentially, execute arbitrary code with the permissions of the user running OpenOffice.org. All users of OpenOffice.org are advised to upgrade to these updated packages, which contain backported patches to correct these issues. All running instances of OpenOffice.org applications must be restarted for this update to take effect.
