Bleeding Edge Threats made available Snort rule that detects some (all?)
exploits using this vulnerability:
http://www.bleedingthreats.net/index.php/2007/03/30/ms-ani-exploit-rule-details-emerging/
I don't know if this rule detects all possible exploits or just one
particular type. Here is a Firekeeper version of the rule, which can
be used to detect sites hosting malicious files:
alert (msg:"BLEEDING-EDGE CURRENT EVENTS MS ANI exploit"; body_content:"|54 53
49 4C 03 00 00 00 00 00 00 00 54 53 49 4C 04 00 00 00 02 02 02 02 61 6E 69 68

Rule is triggered for example by the following images:
