OpenOffice.org is an office productivity suite that includes desktop applications, such as a word processor, spreadsheet application, presentation manager, formula editor, and a drawing program. An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way OpenOffice.org parsed XPM files. An attacker could create a specially-crafted document, which once opened by a local, unsuspecting user, could lead to arbitrary code execution with the permissions of the user running OpenOffice.org. Note: This flaw affects embedded XPM files in OpenOffice.org documents as well as stand-alone XPM files. 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 parsed certain records in Microsoft Word documents. An attacker could create a specially-crafted Microsoft Word document, which once opened by a local, unsuspecting user, could cause OpenOffice.org to crash or, potentially, execute arbitrary code with the permissions of the user running OpenOffice.org. A heap-based buffer overflow flaw, leading to memory corruption, was found in the way OpenOffice.org parsed GIF files. An attacker could create a specially-crafted document, which once opened by a local, unsuspecting user, could cause OpenOffice.org to crash. Note: This flaw affects embedded GIF files in OpenOffice.org documents as well as stand-alone GIF files. 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.
