OpenOffice.org vclmi.dll Integer Overflow
Posted May 16, 2012
Authored by TieLei Wang

A vulnerability is caused due to an integer overflow error in the vclmi.dll module when allocating memory for an embedded image object. This can be exploited to cause a heap-based buffer overflow via, for example using a specially crafted JPEG object within a DOC file. 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.
