Multiple vulnerabilities have been reported in OpenOffice.org, which can be exploited by malicious people to compromise a user's system.
1) An integer overflow error in the vclmi.dll module when allocating memory for an embedded image object can be exploited to cause a heap-based buffer overflow e.g. via a specially crafted JPEG object within a document file.
2) An input validation error in the WPXContentListener::_closeTableRow() function within WPXContentListener.cpp when parsing Wordperfect documents can be exploited to decrement an object pointer arbitrarily.
3) An integer overflow error when processing Escher graphics records can be exploited to cause a buffer overflow via a specially crafted PowerPoint file.
Successful exploitation of the vulnerabilities may allow execution of arbitrary code, but requires tricking a user into opening a malicious file.
The vulnerabilities are reported in version 3.3. Other versions may also be affected.
Solution: Update to version 3.4.
