Title: Multiple BSD Vendor lpd Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
The BSD print protocol daemon, shipped with many systems, contains a remotely exploitable buffer overflow vulnerability. The daemon listens on tcp port 515 and facilitates printing over a network. It is often enabled by default.
The buffer overflow is reportedly due to an inhability to handle maliciously constructed print jobs. If such a job is submitted to a vulnerable server, a buffer overflow can be triggered after the submission when an attacker attempts to view the printer queue.
The printer daemon must be properly configured to exploit this vulnerability. Some systems do not ship with the service enabled, such as OpenBSD and FreeBSD. On systems where the daemon is enabled, the attack must be launched from a host in the '/etc/hosts.equiv' or '/etc/hosts.lpd' files.
If exploited, remote attackers may be able to gain superuser access to vulnerable systems.
