(RHSA-2016:0491) Moderate: foomatic security update

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.
