CVE-2016-5250

Mozilla Firefox before 48.0, Firefox ESR < 45.4 and Thunderbird < 45.4 allow remote attackers to obtain sensitive information about the previously retrieved page via Resource Timing API calls.

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).
