The vulnerability is caused due to an input validation error within the OScan8.ocx / OScan81.ocx ActiveX control when handling arguments passed to the "InitX()" method. This can be exploited to cause a heap-based buffer overflow by prepending two "%" characters to the argument of the affected method. Successful exploitation allows execution of arbitrary code. The vulnerability is reported in version 8.0. Other versions may also be affected. SOLUTION: Update to the latest version (OScan82.ocx). http://www.bitdefender.com/scan8/ie.html PROVIDED AND/OR DISCOVERED BY: Greg Linares, eEye Digital Security CHANGELOG: 2007-11-22: Added CVE identifier.
