Description

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.
