Package : lpr-ppd
Vulnerability : buffer overflow
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.

For the stable distribution (woody) this problem has been fixed in
version 0.72-2.1.

The old stable distribution (potato) does not contain lpr-ppd packages.

For the stable distribution (sid) this problem has been fixed in
version 0.72-3.

We recommend that you upgrade your lpr-ppd package immediately.
