Well Yes last time i made a mp3 crash working upto 6.20 i don't know if it working on 6.30/6.31
But this time ive made a TIFF Crash.
I doubt it is exploitable but i will use psplink to see the results, i will post a image here

EDIT: this tiff has a breakpoint.

happens to the tiff with jpeg compression, I have two tiff, one could be valid, otherwise it produces two accident and the other to cease work on the, by now a vsh exploit is not very useful

no.
its rather Simple to get crashes but is annoying. if you want to look for a Tiff with a Better Chance of it being exploitable look in the Tiff Bug list, get one of them bugs in ur tiff see if it crashes if not keep the bug and make it crash. Smile
and ive got a rather interesting crash somewhere else Smile ill post it soon
