Package : lpr-ppd

Problem-Type : local
Debian-specific: no
CVE Id : CAN-2003-0144

A buffer overflow has been discovered in lpr, a BSD lpr/lpd line
printer spooling system. This problem can be exploited by a local
user to gain root privileges, even if the printer system is set up
properly.

version 0.72-2.1.
