Microsoft Windows Common AVI ActiveX control is prone to a remote buffer-overflow vulnerability. Remote attackers can exploit this issue to execute arbitrary code in the context of the application using the ActiveX control (typically Internet Explorer). Successful exploits will compromise the application and possibly the underlying computer. Failed attacks will cause denial-of-service conditions.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.

Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Set web browser security to disable the execution of script code or active content.
Since a successful exploit of this issue requires malicious code to execute in web clients, consider disabling support for script code and active content within the client browser. Note that this mitigation tactic might adversely affect legitimate websites that rely on the execution of browser-based script code.

Implement multiple redundant layers of security.
Memory-protection schemes (such as nonexecutable stack and heap configurations and randomly mapped memory segments) will complicate exploits of memory-corruption vulnerabilities.

The vendor has released an advisory and updates to address this issue. Please see the references for more information.
