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.

Debian GNU/Linux 2.1 alias slink
