'Name' => 'Irfanview JPEG2000 <= v4.3.2.0 jp2 Stack Buffer Overflow',

'Description'=> %q{

This module exploits a stack-based buffer overflow vulnerability in

version <= 4.3.2.0 of Irfanview's JPEG2000.dll plugin. This exploit has been

tested on a specific version of irfanview (v4.3.2), although other versions may

work also. The vulnerability is triggered via parsing an invalid qcd chunk

structure and specifying a malformed qcd size and data.

Payload delivery and vulnerability trigger can be executed in multiple ways.

The user can double click the file, use the file dialog, open via the icon

and drag/drop the file into Irfanview\'s window. An egg hunter is used for

stability.
