Esteemed hackers,
we havehad set up the 27c3 network so that it willwould crash OS X and iPhones:
This is this year's mystery challenge, and there are tickets for the Chaos Communication Camp in summer 2011 to win. We have prizes for the first person each to publish:
-
a pcap dumphttp://www.attilla.nl/osx_crash/association_response_crash.pcap -
a way to replay that dump in order to crash a macNot possible by replaying some data -
a stack trace with registers of the crashsolved, see http://pastebin.ca/2030027 - code execution:
Not possible, since it's a division by zero.wrong: it is a division overflow. the div64by32 result is larger than 32bits.
Accepted input is a link to a file with the solution, together with a SHA-256 sum of said file, on twitter. Add a #27c3 #0day tag. Timestamp on twitter counts.
Bug has been submitted at bugtraq with full details, but still has to go through the moderation queue..
Ladies and gentlemen, start your debuggers!
