foomatic-filters: User-assisted execution of arbitrary code

Background

The foomatic-filters package contains wrapper scripts which are designed to be used with Foomatic.

Description

The foomatic-rip filter improperly handles command-line arguments, including those issued by FoomaticRIPCommandLine fields in PPD files.

Impact

A remote attacker could entice a user to open a specially crafted PPD file, possibly resulting in execution of arbitrary code with the privileges of the system user “lp”.

Workaround

There is no known workaround at this time.

Resolution

All foomatic-filters users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose
 ">=net-print/foomatic-filters-4.0.9"
