CVE-2012-2334 Vulnerabilities related to malformed Powerpoint files
in OpenOffice.org 3.3.0
Reference: http://www.openoffice.org/security/cves/CVE-2012-2334.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:
A review of the code in filter/source/msfilter msdffimp.cxx revealed
some unchecked memory allocations, which could be exploited via
malformed Powerpoint graphics records ("escher") to cause bad_alloc
exceptions. From this vulnerability a denial of service attack is
possible.
Mitigation
OpenOffice.org 3.3.0 and 3.4 beta users are advised to upgrade to
Apache OpenOffice 3.4. Users who are unable to upgrade immediately
should be cautious when opening untrusted documents.
