The Mozilla Project reports :

Security researcher Khalil Zhani reported that a maliciously crafted vp9 format video could be used to trigger a buffer overflow while parsing the file. This leads to a potentially exploitable crash due to a flaw in the libvpx library.

Updated firefox packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5, 6, and 7.

Red Hat Product Security 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.

[Updated 25 August 2014] This erratum previously included an incorrect list of fixed issues. The issue list has been updated to reflect the CVEs that were fixed in this update. The firefox packages provided by this advisory have not been modified in any way.

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-2015-4500, CVE-2015-4506, CVE-2015-4509, CVE-2015-4511, CVE-2015-4517, CVE-2015-4521, CVE-2015-4522, CVE-2015-7174, CVE-2015-7175, CVE-2015-7176, CVE-2015-7177, CVE-2015-7180)

Two information leak flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to disclose sensitive information or, in certain cases, crash.
(CVE-2015-4519, CVE-2015-4520)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Andrew Osmond, Olli Pettay, Andrew Sutherland, Christian Holler, David Major, Andrew McCreight, Cameron McCormack, Khalil Zhani, Atte Kettunen, Ronald Crane, Mario Gomes, and Ehsan Akhgari as the original reporters of these issues.

 - A flaw exists that is triggered when handling add-on installation using 'data:' URLs. With a specially crafted web page, a context-dependent attacker can bypass the install permission prompt for add-ons and install add-ons from malicious sources. (CVE-2015-4498)

USN-2743-1 fixed vulnerabilities in Firefox. Future Firefox updates will require all addons be signed and unity-firefox-extension, webapps-greasemonkey and webaccounts-browser-extension will not go through the signing process. Because these addons currently break search engine installations (LP: #1069793), this update permanently disables the addons by removing them from the system.

We apologize for any inconvenience.

From Red Hat Security Advisory 2015:1834 :

Updated firefox packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5, 6, and 7.

Red Hat Product Security 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.

[Updated 25 August 2014] This erratum previously included an incorrect list of fixed issues. The issue list has been updated to reflect the CVEs that were fixed in this update. The firefox packages provided by this advisory have not been modified in any way.

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-2015-4500, CVE-2015-4506, CVE-2015-4509, CVE-2015-4511, CVE-2015-4517, CVE-2015-4521, CVE-2015-4522, CVE-2015-7174, CVE-2015-7175, CVE-2015-7176, CVE-2015-7177, CVE-2015-7180)

Two information leak flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to disclose sensitive information or, in certain cases, crash.
(CVE-2015-4519, CVE-2015-4520)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Andrew Osmond, Olli Pettay, Andrew Sutherland, Christian Holler, David Major, Andrew McCreight, Cameron McCormack, Khalil Zhani, Atte Kettunen, Ronald Crane, Mario Gomes, and Ehsan Akhgari as the original reporters of these issues.

All Firefox users should upgrade to these updated packages, which contain Firefox version 38.3.0 ESR, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.
