Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated cups packages that fix multiple security issues and several bugs are 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 for each vulnerability from the CVE links in the References section.

CUPS provides a portable printing layer for Linux, UNIX, and similar operating systems.

A cross-site scripting (XSS) flaw was found in the CUPS web interface.
An attacker could use this flaw to perform a cross-site scripting attack against users of the CUPS web interface. (CVE-2014-2856)

It was discovered that CUPS allowed certain users to create symbolic links in certain directories under /var/cache/cups/. A local user with the 'lp' group privileges could use this flaw to read the contents of arbitrary files on the system or, potentially, escalate their privileges on the system. (CVE-2014-3537, CVE-2014-5029, CVE-2014-5030, CVE-2014-5031)

The CVE-2014-3537 issue was discovered by Francisco Alonso of Red Hat Product Security.

These updated cups packages also include several bug fixes. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.6 Technical Notes, linked to in the References section, for information on the most significant of these changes.

All cups users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the cupsd daemon will be restarted automatically.

Solution

Update the affected packages.
