Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.61%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The appendChild function in Mozilla Firefox before 3.6.20, Thunderbird 3.x before 3.1.12, SeaMonkey 2.x, and possibly other products does not properly handle DOM objects, which allows remote attackers to execute arbitrary code via unspecified vectors that lead to dereferencing of a "dangling pointer."
