Package: lpr
Vulnerability type: remote exploit
Debian-specific: no

The version of lpr that was distributed with Debian GNU/Linux 2.1
and the updated version released in 2.1r4 have a two security
problems:

* the client hostname wasn't verified properly, so if someone is able to
  control the DNS entry for their IP he could fool lpr into granting
  access.
* it was possible to specify extra options to sendmail which could be
  used to specify another configuration file. This can be used to
  gain root access.

Both problems have been fixed in 0.48-0.slink1 . We recommend you upgrade
your lpr package immediately.
