CVE-2010-3766
Use-after-free vulnerability in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, allows remote attackers to execute arbitrary code via vectors involving a change to an nsDOMAttribute node.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.00%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
