CVE-2015-4486
The decrease_ref_count function in libvpx in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read) via malformed WebM video data.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.61%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
