CVE-2015-2743
PDF.js in Mozilla Firefox before 39.0 and Firefox ESR 31.x before 31.8 and 38.x before 38.1 enables excessive privileges for internal Workers, which might allow remote attackers to execute arbitrary code by leveraging a Same Origin Policy bypass.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.74%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
