"The version of Mozilla Firefox ESR 31.x installed on the remote
Windows host is prior to 31.5.2. 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',

attacker, using a specially crafted web page, can exploit this to
execute arbitrary code by reading and writing to memory.");
