-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 CVE-2012-2149 OpenOffice.org memory overwrite vulnerability Reference: http://www.openoffice.org/security/cves/CVE-2012-2149.html Severity: Important Vendor: The Apache Software Foundation Versions Affected: OpenOffice.org 3.3 and 3.4 Beta, on all platforms. Earlier versions may be also affected. Description: Effected versions of OpenOffice.org use a customized libwpd that has a memory overwrite vulnerability that could be exploited by a specially crafted Wordperfect WPD-format document, potentially leading to arbitrary-code execution at application user privilege level. Mitigation OpenOffice.org 3.3.0 and 3.4 beta users are advised to upgrade to Apache OpenOffice 3.4, where WPD files are ignored. Users who are unable to upgrade immediately should be cautious when opening untrusted WPD documents.
