Microsoft Security Advisory (912840): Remote Code Execution from WMF files
Wednesday, December 28th, 2005This is the official Security Advisory from Microsoft.
Microsoft is investigating new public reports of a possible vulnerability in Windows. Microsoft will continue to investigate the public reports to help provide additional guidance for customers.
Microsoft is aware of the public release of detailed exploit code that could allow an attacker to execute arbitrary code in the security context of the logged-on user, when such user is visiting a Web site that contains a specially crafted Windows Metafile (WMF) image. An attacker would have no way to force users to visit a malicious Web site. Instead, an attacker would have to persuade them to visit the Web site, typically by getting them to click a link that takes them to the attacker’s Web site.
Customers are encouraged to keep their antivirus software up to date. The Microsoft Windows AntiSpyware (Beta) can also help protect your system from spyware and other potentially unwanted software. We will continue to investigate these public reports.
Upon completion of this investigation, Microsoft will take the appropriate action to help protect our customers. This will include providing a security update through our monthly release process or providing an out-of-cycle security update, depending on customer needs.
Microsoft encourages users to exercise caution when they open e-mail and links in e-mail from untrusted sources. For more information about Safe Browsing, visit the Trustworthy Computing Web site.
We continue to encourage customers to follow our Protect Your PC guidance of enabling a firewall, applying software updates and installing antivirus software. Customers can learn more about these steps at the Protect Your PC Web site.
Customers who believe they may have been affected by this issue can contact Product Support Services. You can contact Product Support Services in the United States and Canada at no charge using the PC Safety line (1 866-PCSAFETY). Customers outside of the United States and Canada can locate the number for no-charge virus support by visiting the Microsoft Help and Support Web site.
