http://gamingzone.ubisoft.comshame on me for having found a couple of buffer overflow in a so old activex component... well it was just a test so don't worry I'm not crazy but was useless to keep it sleeping on my hard-disk.
note that it's highly probable that is also possible to load the so called Language_english.dll file directly but at the moment it didn't seem, oh well who cares.
in attachment there are the 3 bugs: 2 buffer overflows and a limited directory traversal
GS4 is now almost abandoned but it was an important component for the players of games like Ghost Recon and Rainbow Six
