JSON

Inside the JavaScript parser, a cast of an integer to a narrower type can
result in data read from outside the buffer being parsed. This usually
results in a non-exploitable crash, but can leak a limited amount of
information from memory if it matches JavaScript identifier syntax. This
vulnerability affects Firefox < 56.
