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 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)
All foomatic users should upgrade to this updated package, which contains
a backported patch to resolve this issue.
