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 Red Hat Enterprise Linux 5, the "background-repeat" CSS (Cascading Style Sheets) property did not work (such images were not displayed and repeated as expected). (BZ#698313) 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. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 698313 - "background-repeat" css property isn't rendered well in Firefox 3.6.x 714576 - CVE-2011-2364, CVE-2011-2365, CVE-2011-2374, CVE-2011-2375, CVE-2011-2376 Mozilla Miscellaneous memory safety hazards (MFSA 2011-19) 714577 - CVE-2011-2373 Mozilla Use-after-free vulnerability when viewing XUL document with script disabled (MFSA 2011-20) 714580 - CVE-2011-2371 Mozilla Integer overflow and arbitrary code execution (MFSA 2011-22) 714581 - CVE-2011-0083 CVE-2011-0085 CVE-2011-2363 Mozilla Multiple dangling pointer vulnerabilities (MFSA 2011-23) 714583 - CVE-2011-2362 Mozilla Cookie isolation error (MFSA 2011-24) 714929 - CVE-2011-2377 Mozilla Crash caused by corrupted JPEG image (MFSA 2011-21) 6.
