'Name' => 'Facebook Photo Uploader 4 ActiveX Control Buffer Overflow',
'Description' => %q{
This module exploits a stack buffer overflow in Facebook Photo Uploader 4.
By sending an overly long string to the "ExtractIptc()" property located
in the ImageUploader4.ocx (4.5.57.0) Control, an attacker may be able to execute
arbitrary code.
