Scientific Linux Security Update : firefox on SL4.x, SL5.x, SL6.x i386/x86_64

critical Nessus Plugin ID 61070

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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

A flaw was found in the way Firefox handled malformed JPEG images. A website containing a malicious JPEG image could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2011-2377)

Multiple dangling pointer flaws were found in Firefox. 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-2011-0083, CVE-2011-0085, CVE-2011-2363)

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-2011-2364, CVE-2011-2365, CVE-2011-2374, CVE-2011-2375, CVE-2011-2376)

An integer overflow flaw was found in the way Firefox handled JavaScript Array objects. A website containing malicious JavaScript could cause Firefox to execute that JavaScript with the privileges of the user running Firefox. (CVE-2011-2371)

A use-after-free flaw was found in the way Firefox handled malformed JavaScript. A website containing malicious JavaScript could cause Firefox to execute that JavaScript with the privileges of the user running Firefox. (CVE-2011-2373)

It was found that Firefox could treat two separate cookies as interchangeable if both were for the same domain name but one of those domain names had a trailing '.' character. This violates the same-origin policy and could possibly lead to data being leaked to the wrong domain. (CVE-2011-2362)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.6.18. You can find a link to the Mozilla advisories in the References section of this erratum.

This update also fixes the following bug :

- With previous versions of Firefox on Scientific Linux 5, the 'background-repeat' CSS (Cascading Style Sheets) property did not work (such images were not displayed and repeated as expected).

All Firefox users should upgrade to these updated packages, which contain Firefox version 3.6.18, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

Solution

Update the affected firefox, xulrunner and / or xulrunner-devel packages.
