Severity: Important

Vendor: The Apache Software Foundation

Versions Affected:

Apache OpenOffice 3.4.0, all languages, all platforms.
Earlier versions of OpenOffice.org may be also affected.

Description:

When OpenOffice reads an ODF document, it first loads and processes
an XML stream within the file called the manifest. Apache OpenOffice
3.4.0 has logic errors that allows a carefully crafted manifest to
cause reads and writes beyond allocated buffers.

No specific exploit has been demonstrated in this case, though such
flaws generally are conducive to exploitation, possibly including
denial of service and elevation of privilege.

Mitigation

when opening untrusted ODF documents.
