Summary

Foomatic is a comprehensive, spooler-independent database of printers, printer drivers, and driver descriptions. The package also includes spooler-independent command line interfaces to manipulate queues and to print files and manipulate print jobs. foomatic-rip is a print filter written in Perl.
An input sanitization flaw was found in the foomatic-rip print filter. An attacker could submit a print job with the username, title, or job options set to appear as a command line option that caused the filter to use a specified PostScript printer description (PPD) file, rather than the administrator-set one. This could lead to arbitrary code execution with the privileges of the "lp" user. (CVE-2011-2697)
All foomatic users should upgrade to this updated package, which contains a backported patch to resolve this issue.
