"The LPRng print spooler, as shipped in Red Hat Linux Advanced Server
2.1, accepts all remote print jobs by default. Updated LPRng packages
are available to fix this issue.

With its default configuration, LPRng will accept job submissions from
any host, which is not appropriate in a workstation environment. We
are grateful to Matthew Caron for pointing out this configuration
problem.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2002-0378 to this issue.

The updated packages from this advisory change the job submission
policy (in /etc/lpd.perms) so that jobs from remote hosts are refused
by default.

Those running print servers may want to adjust this policy as
appropriate, for example to give access to certain hosts or subnets.
For details on how to do this, see the lpd.perms(5) man page.

Please note that default installations of Red Hat Linux Advanced
Server 2.1 include ipchains rules blocking remote access to the print
spooler IP port; as a result those installations already reject remote
job submissions.

NOTE: There are special instructions for installing this update at the
end of the 'Solution' section."
