CVE-2016-2807

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 46.0, Firefox ESR 38.x before 38.8, and Firefox ESR 45.x before 45.1 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Updated firefox packages fix security vulnerabilities:

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-2016-2805, CVE-2016-2806, CVE-2016-2807, CVE-2016-2808, CVE-2016-2814).

Multiple flaws were found in the processing of malformed web content. A web page containing malicious content could cause Thunderbird to crash or, potentially, execute arbitrary code with the privileges of the user running Thunderbird (CVE-2016-2805, CVE-2016-2807, CVE-2016-2818).

If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2016-2804, CVE-2016-2806, CVE-2016-2807)

An invalid write was discovered when using the JavaScript .watch() method in some circumstances.
