Folks at @vupen seems to have it exploited the hard way. "We successfully exploited the recent Sudo local root / format string vuln including full bypass of FORTIFY_SOURCE #GotRoot"
Yep, looks like. I hope it will not be like with the Chrome Sandbox bypass that was achieved through a flash 0day :-) Maybe this time they exploited sudo through CUPS 1.1 ahah antisnatchor

It will just be noisy in dmesg due to all the segfaults while brute forcing the right values. cheers, joernchen_______________________________________________ Full-Disclosure - We believe in it.
