| 5164 | util-linux setpwnam.c Open File Descriptor Race The util-linux utilities contain a flaw that may allow a malicious user to gain elevated priviliges. The race condition can be triggered if the attacker is able to successfully execute a complex attack-sequence using /usr/bin/chfn or usr/bin/chsh. The attack requires that the system administrator interacts with the system. He specifically needs to remove /etc/ptmp before the attacker can complete the attack.
