3. Description:

 

Mozilla Firefox is an open source web browser.

 

This update upgrades Firefox to version 45.5.0 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-2016-5296, CVE-2016-5297, CVE-2016-9066, CVE-2016-5291,

CVE-2016-5290)

 

* A flaw was found in the way Add-on update process was handled by Firefox.

A Man-in-the-Middle attacker could use this flaw to install a malicious

signed add-on update. (CVE-2016-9064)

 

Red Hat would like to thank the Mozilla project for reporting these issues.

Upstream acknowledges Abhishek Arya, André Bargull, Samuel Groß, Yuyang

Zhou, Olli Pettay, Christian Holler, Ehsan Akhgari, Jon Coppeard, Gary
