Discovered: 01.05.10. Mach exception handling suffers from a vulnerability that allows an attacker to gain access to the memory of a suid process (set user identifier). Due to a vulnerability that is similar to CVE-2006-4392 (found by Dino Dai Zovi of Matasano Security), it is possible for a suid process to inherit the Mach exception ports of the parent.
