Description

This module exploits a buffer overflow vulnerability in the
LoadAniIcon() function in USER32.dll. The flaw can be triggered through
Internet Explorer 6 and 7 by using the CURSOR style sheet directive
to load a malicious .ANI file. The module can also exploit Mozilla
Firefox by using a UNC path in a moz-icon URL and serving the .ANI file
over WebDAV. The vulnerable code in USER32.dll will catch any
exceptions that occur while the invalid cursor is loaded, causing the
exploit to silently fail when the wrong target has been chosen.

This vulnerability was discovered by Alexander Sotirov of Determina
and was rediscovered, in the wild, by McAfee.
