SophosLabs comments	This advisory encompasses the way memory is accessed by Microsoft Office and Internet Explorer when loading Access ActiveX controls. Exploiting this vulnerability gives an attacker the same rights and privileges as the user running the Access ActiveX control. The fact that these vulnerabilities have not been publicly disclosed, and that we are yet to see any malware that exploit these issues have been considered when assigning the SophosLabs threat rating of Medium.
SophosLabs testing result	N/A
Currently known exploits	At the time of writing SophosLabs have not observed any malware attempting to exploit this vulnerability. Should this situation change samples will be analyzed and we will take action as necessary.
