Almost all 64-bit machines are affected, and ‘Ac1db1tch3z’ (classy) published code to let any local user get a root shell. Ac1db1tch3z’s exploit is more malicious than usual because it leaves a backdoor behind for itself to exploit later even if the hole is patched.

According to a report, the problem occurs because the 32-bit call emulation layer does not check whether the call is truly in the Syscall table. Ben Hawkes, who… Continue reading
