Mozilla Firefox < 36.0.3 / Firefox ESR < 31.5.2 JIT Code Execution



The remote host has a web browser that is affected by a remote code execution vulnerability.


Versions of Mozilla Firefox earlier than 36.0.3 (or ESR version 31.5.2) are 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.


Upgrade to Firefox 36.0.3 (or Firefox ESR version 31.5.2, as appropriate), or later.
