Descriptions

When multiple WASM threads had a reference to a module, and were looking up exported functions, one WASM thread could have overwritten another's entry in a shared stub table, resulting in a potentially exploitable crash. This vulnerability affects Firefox < 82.

Cuando múltiples subprocesos WASM presentaban una referencia a un módulo y buscaban funciones exportadas, un subproceso WASM podría haber sobrescrito la entrada de otro en una tabla de códigos auxiliares compartida, lo que resultó en un bloqueo potencialmente explotable.&#xa0;Esta vulnerabilidad afecta a Firefox versiones anteriores a 82
