Debian Linux in.uucpd denial of service

debian-in-uucpd-dos (9230) The risk level is classified as MediumMedium Risk


Debian Linux is vulnerable to a denial of service attack caused by a buffer overflow in the in.uucpd daemon (an authentication agent in the uucp package). By sending an overly long string to the in.uucpd daemon, a remote attacker can overflow a buffer and cause the daemon to crash. The service must be restarted to regain normal functionality.
