Descriptions

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.

La vulnerabilidad afecta a Firefox ESR en versiones anteriores a la 60.2.2 y Firefox en versiones anteriores a la 62.0.3.
