Foomatic: Arbitrary command execution in foomatic-rip filter The foomatic-rip filter in foomatic-filters contains a vulnerability which may allow arbitrary command execution on the print server. foomatic September 20, 2004 September 20, 2004: 01 64166 remote 3.0.2 3.0.1 3.0.2 3.0.1

Foomatic is a system for connecting printer drivers with spooler systems such as CUPS and LPD. The foomatic-filters package contains wrapper scripts which are designed to be used with Foomatic.

There is a vulnerability in the foomatic-filters package. This vulnerability is due to insufficient checking of command-line parameters and environment variables in the foomatic-rip filter.

This vulnerability may allow both local and remote attackers to execute arbitrary commands on the print server with the permissions of the spooler (oftentimes the "lp" user).

There is no known workaround at this time.

All foomatic users should upgrade to the latest version:

# emerge sync # emerge -pv ">=net-print/foomatic-3.0.2" # emerge ">=net-print/foomatic-3.0.2"

PLEASE NOTE: You should update foomatic, instead of foomatic-filters. This will help to ensure that all other foomatic components remain functional.
