Microsoft published a security advisory about vulnerability in Microsoft Video ActiveX Control that could allow remote code execution
Microsoft is investigating a privately reported vulnerability in Microsoft Video ActiveX Control. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. When using Internet Explorer, code execution is remote and may not require any user intervention.Microsoft Security Advisory (972890)
We are aware of attacks attempting to exploit the vulnerability.
Our investigation has shown that there are no by-design uses for this ActiveX Control in Internet Explorer which includes all of the Class Identifiers within the msvidctl.dll that hosts this ActiveX Control. For Windows XP and Windows Server 2003 customers, Microsoft is recommending removing support for this ActiveX Control within Internet Explorer using all the Class Identifiers listed in the Workaround section. Though unaffected by this vulnerability, Microsoft is recommending that Windows Vista and Windows Server 2008 customers remove support for this ActiveX Control within Internet Explorer using the same Class Identifiers as a defense-in-depth measure.
Customers may prevent the Microsoft Video ActiveX Control from running in Internet Explorer, either manually using the instructions in the Workaround section or automatically using the solution found in Microsoft Knowledge Base Article 972890. By preventing the Microsoft Video ActiveX Control from running in Internet Explorer, there is no impact to application compatibility.
We are actively working with partners in our Microsoft Active Protections Program (MAPP) to provide information that they can use to provide broader protections to customers.
Microsoft is currently working to develop a security update for Windows to address this vulnerability and will release the update when it has reached an appropriate level of quality for broad distribution.
