(The 0day as promised in the subject line is attached. If you can't see it, then it worked!)
Did not work for me, shows as a regular JPEG, although I fiddled with it a bit... looks like it's meant to target this code, right? s += state.last_dc_val[ci]; state.last_dc_val[ci] = s; /* Scale and output the coefficient (assumes jpeg_natural_order[0]=0) */ (*block)[0] = (JCOEF) (s << Al); The bug is pretty subtle, took me a while to figure it out. Kudos. /mz _______________________________________________ Dailydave mailing list Dailydave () lists immunityinc com https://lists.immunityinc.com/mailman/listinfo/dailydave
