Heap-based buffer overflow in the nsHTMLReflowState::CalculateHypotheticalBox function in Mozilla Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.85%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
