CentOS 5 / 6 : firefox / xulrunner (CESA-2013:0981)

critical Nessus Plugin ID 66996

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated firefox packages that fix several security issues are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having critical 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.

Mozilla Firefox is an open source web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2013-1682, CVE-2013-1684, CVE-2013-1685, CVE-2013-1686, CVE-2013-1687, CVE-2013-1690)

It was found that Firefox allowed data to be sent in the body of XMLHttpRequest (XHR) HEAD requests. In some cases this could allow attackers to conduct Cross-Site Request Forgery (CSRF) attacks.
(CVE-2013-1692)

Timing differences in the way Firefox processed SVG image files could allow an attacker to read data across domains, potentially leading to information disclosure. (CVE-2013-1693)

Two flaws were found in the way Firefox implemented some of its internal structures (called wrappers). An attacker could use these flaws to bypass some restrictions placed on them. This could lead to unexpected behavior or a potentially exploitable crash.
(CVE-2013-1694, CVE-2013-1697)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Gary Kwong, Jesse Ruderman, Andrew McCreight, Abhishek Arya, Mariusz Mlynski, Nils, Johnathan Kuskos, Paul Stone, Boris Zbarsky, and moz_bug_r_a4 as the original reporters of these issues.

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 17.0.7 ESR. You can find a link to the Mozilla advisories in the References section of this erratum.

All Firefox users should upgrade to these updated packages, which contain Firefox version 17.0.7 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

Solution

Update the affected firefox and / or xulrunner packages.
