An update for firefox is now available for Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6, and Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Critical. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Mozilla Firefox is an open source web browser.

This update upgrades Firefox to version 45.4.0 ESR.

Security Fix(es) :

  • Multiple 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-2016-5257, CVE-2016-5278, CVE-2016-5270, CVE-2016-5272, CVE-2016-5274, CVE-2016-5276, CVE-2016-5277, CVE-2016-5280, CVE-2016-5281, CVE-2016-5284, CVE-2016-5250, CVE-2016-5261)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Samuel Gross, Brian Carpenter, Mei Wang, Ryan Duff, Catalin Dumitru, Mozilla developers, Christoph Diehl, Andrew McCreight, Dan Minor, Byron Campen, Jon Coppeard, Steve Fink, Tyson Smith, Philipp, Carsten Book, Abhishek Arya, Atte Kettunen, and Nils as the original reporters.
