Date Discovered July 6, 2009
Description The Microsoft Active Template Library (ATL) is prone to a remote code-execution vulnerability.
This issue affects a private version of the ATL used internally by Microsoft; components written by other vendors are likely unaffected.
Remote attackers can exploit this issue to execute arbitrary code with the privileges of the user running an application built against the affected library. Failed exploit attempts will result in a denial-of-service condition.
NOTE: This BID was previously titled "Microsoft Windows 'MPEG2TuneRequest' ActiveX Control Remote Code Execution Vulnerability". It has been updated to better reflect the issue.
Run all software as a nonprivileged user with minimal access rights. To mitigate the impact of a successful exploit, run the affected application as a 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 suspicious or anomalous activity. This may help detect malicious actions that an attacker may take after successfully exploiting vulnerabilities in applications. Review all applicable logs regularly.
Do not follow links provided by unknown or untrusted sources. Never accept files or follow links from untrusted or unknown sources, because they may be malicious in nature.
Set web browser security to disable the execution of script code or active content.
To limit exposure to these issues, disable support for client-side scripting and active content. This is especially prudent for untrusted sites in the Internet Zone.
Vendor advisories and updates are available. Please see the references for details.
