Re: Windows MetaFiles still vulnerable

From SANS today:

The orignal exploit site (unionseek.com) is no longer up. But the exploit is being served from various sites all over by now, see the F-Secure Blog on »www.f-secure.com/weblog/ for an update on the versions of the exploit found in the wild.

Regarding DEP (Data Execution Protection) of XPSP2, the default settings of DEP will not prevent this exploit from working. Comments we have received in the meantime suggest that if you enable DEP to cover all programs (as documented on Microsoft Technet ), the WMF exploit attempt will result in a warning and not run on its own.

While the original exploit only refered to the Microsoft Picture and Fax Viewer, current information is that any application which automatically displays or renders WMF files is vulnerable to the problem. This includes Google Desktop, if the indexing function finds one of the exploit WMFs on the local hard drive - see the F-Secure Weblog mentioned above for details.
********************************
I know of some guys who downloaded the file "wmf_exp.wmf" to further investigate it.
