GCVE-110-MAGEIA-2016-379

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). An existing mitigation of timing side-channel attacks in NSS before 3.26.1 is insufficient in some circumstances (CVE-2016-9074).
