CVE-2015-7221
Buffer overflow in the nsDeque::GrowCapacity function in xpcom/glue/nsDeque.cpp in Mozilla Firefox before 43.0 might allow remote attackers to cause a denial of service or possibly have unspecified other impact by triggering a deque size change.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.51%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
