"From Red Hat Security Advisory 2016:0491 :

An updated foomatic package that fixes three security issues is now
available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available from the
CVE links in the References section.

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.

It was discovered that the unhtmlify() function of foomatic-rip did
not correctly calculate buffer sizes, possibly leading to a heap-based
memory corruption. A malicious attacker could exploit this flaw to
cause foomatic-rip to crash or, possibly, execute arbitrary code.
(CVE-2010-5325)

It was discovered that foomatic-rip failed to remove all shell special
characters from inputs used to construct command lines for external
programs run by the filter. An attacker could possibly use this flaw
to execute arbitrary commands. (CVE-2015-8327, CVE-2015-8560)

All foomatic users should upgrade to this updated package, which
contains backported patches to correct these issues."
