CVE-2012-4187
Mozilla Firefox before 16.0, Firefox ESR 10.x before 10.0.8, Thunderbird before 16.0, Thunderbird ESR 10.x before 10.0.8, and SeaMonkey before 2.13 do not properly manage a certain insPos variable, which allows remote attackers to execute arbitrary code…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.84%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
