Background ========== 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. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-print/foomatic <= 3.0.1 >= 3.0.2 2 net-print/foomatic-filters <= 3.0.1 >= 3.0.2 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== 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. Impact ====== 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). Workaround ========== There is no known workaround at this time. Resolution ========== 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.
