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-2012-4214, CVE-2012-4215, CVE-2012-4216, CVE-2012-5829,
CVE-2012-5830, CVE-2012-5833, CVE-2012-5835, CVE-2012-5839, CVE-2012-5840,
CVE-2012-5842)

A buffer overflow flaw was found in the way Firefox handled GIF (Graphics
Interchange Format) images. A web page containing a malicious GIF image
could cause Firefox to crash or, possibly, execute arbitrary code with the
privileges of the user running Firefox. (CVE-2012-4202)

A flaw was found in the way the Style Inspector tool in Firefox handled
certain Cascading Style Sheets (CSS). Running the tool (Tools -> Web
Developer -> Inspect) on malicious CSS could result in the execution of
HTML and CSS content with chrome privileges. (CVE-2012-4210)

A flaw was found in the way Firefox decoded the HZ-GB-2312 character
encoding. A web page containing malicious content could cause Firefox to
run JavaScript code with the permissions of a different website.
(CVE-2012-4207)

A flaw was found in the location object implementation in Firefox.
Malicious content could possibly use this flaw to allow restricted content
to be loaded by plug-ins. (CVE-2012-4209)

A flaw was found in the way cross-origin wrappers were implemented.
Malicious content could use this flaw to perform cross-site scripting
attacks. (CVE-2012-5841)

A flaw was found in the evalInSandbox implementation in Firefox. Malicious
content could use this flaw to perform cross-site scripting attacks.
(CVE-2012-4201)

For technical details regarding these flaws, refer to the Mozilla security
advisories for Firefox 10.0.11 ESR. You can find a link to the Mozilla
advisories in the References section of this erratum.

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Abhishek Arya, miaubiz, Jesse Ruderman, Andrew
McCreight, Bob Clary, Kyle Huey, Atte Kettunen, Mariusz Mlynski, Masato
Kinugawa, Bobby Holley, and moz_bug_r_a4 as the original reporters of these
issues.

All Firefox users should upgrade to these updated packages, which contain
Firefox version 10.0.11 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.
