The correction for CAN-2003-0144 for the old stable distribution (potato) was a little bit too strict apparently and this update corrects this.

Summary

The correction for CAN-2003-0144 for the old stable distribution
(potato) was a little bit too strict apparently and this update
corrects this. For completeness here is the advisory text:

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 2000.05.07-4.3.

For the old stable distribution (potato) this problem has been fixed
in version 0.48-1.2.

For the stable distribution (sid) this problem has been fixed in
version 2000.05.07-4.20.

We recommend that you upgrade your lpr package immediately.
