Description
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.
