CVE-2016-1973
Race condition in the GetStaticInstance function in the WebRTC implementation in Mozilla Firefox before 45.0 might allow remote attackers to execute arbitrary code or cause a denial of service (use-after-free) via unspecified vectors.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.98%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
