A vulnerability where the JavaScript JIT compiler inlines
Array.prototype.push with multiple arguments that results in the stack
pointer being off by 8 bytes after a bailout. This leaks a memory address
to the calling function which can be used as part of an exploit inside the
sandboxed content process. This vulnerability affects Firefox ESR < 60.2.2
and Firefox < 62.0.3.
