Microsoft Office OWC10 ActiveX Control Loading and Unloading Heap Corruption Vulnerability

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of Microsoft Office. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists when loading and unloading the vulnerable control (0002E543-0000-0000-C000-000000000046) and results in transfer of control to unallocated memory. This issue can be exploited to execute arbitrary code under the context of the currently logged in user user.
