The version of Mozilla Firefox installed on the remote Windows host is prior to 36.0.3. It is, therefore, affected by a remote code execution vulnerability due to an out-of-bounds error in typed array bounds checking within ‘asmjs/AsmJSValidate.cpp’, which relates to just-in-time compilation for JavaScript. A remote attacker, using a specially crafted web page, can exploit this to execute arbitrary code by reading and writing to memory.
