Metasploit vs ANI

Two new exploit modules are available for version 3.0 of the Metasploit 
Framework. These modules can be obtained by using the 'Online Update' 
feature in Windows and the 'svn update' command on Unix-like systems.

Matt Miller posted to the Metasploit Blog about our ANI efforts:
http://blog.metasploit.com/

The two exploits can be viewed in the svn repository at metasploit.com:
http://metasploit.com/svn/framework3/trunk/modules/exploits/windows/browser/ani_loadimage_chunksize.rb
http://metasploit.com/svn/framework3/trunk/modules/exploits/windows/email/ani_loadimage_chunksize.rb

Nice work!

I've just been testing ANI/HTTP payload against XPSP2 and Vista, and the
Web page seems somewhat "corrupted". As a result, IE displays ASCII
characters without even crashing.

I cannot even see the "anih" header. The page might be GZIP'ed even if
default options are set to turn off all evasion techniques. What do you
think ?
