CVE-2006-3801
Mozilla Firefox 1.5 before 1.5.0.5 and SeaMonkey before 1.0.3 does not properly clear a JavaScript reference to a frame or window, which leaves a pointer to a deleted object that allows remote attackers to execute arbitrary native code.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.43%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
