Red Hat: An updated foomatic package fixes one security issue is now available

Foomatic is a comprehensive, spooler-independent database of printers, printer drivers, and driver descriptions. 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. Updated packages are available from updates.redhat.com.

3. Description:

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 C.

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-2011-2964)
