We just released a new version of the Metasploit Framework exploit module for the Escape/SetAbortFunc code execution flaw. This module now pads the Escape() call with random WMF records. You may want to double check your IDS signatures -- most of the ones I saw today could be easily bypassed or will false positive on valid graphic files. Available via msfupdate, the 2.5 snapshot, or straight from the web site: http://metasploit.com/projects/Framework/exploits.html#ie_xp_pfv_metafile -HD
