red hat
November 16, 2016
An update for firefox is now available for Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6, and Red Hat Enterprise Linux 7
Solution
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258

take effect.
Summary
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.
