CVE-2016-2804
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 46.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.84%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
