CVE-2014-1514 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. vmtypedarrayobject.cpp in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 does not validate the length of the destination array before a copy operation, which allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds write and application crash) by triggering incorrect use of the TypedArrayObject class.. EPSS estimates a 6.09% chance of exploitation in the next 30 days.
