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" Src: https://twitter.com/#!/VUPEN/status/165454997444767745 Cheers, -Román joernchen of Phenoelit escribió:

On systems with ASLR and a non-executable stack it should be even harder.nasty thing is: it's a local exploit so you got nearly unlimited tries for free =). It will just be noisy in dmesg due to all the segfaults while brute forcing the right values. cheers, joernchen
