Summary
  • (es) Se encontró un fallo de lectura fuera de los límites en Shim debido a la falta de una verificación de límites adecuada durante la carga de un binario PE. Esta falla permite a un atacante cargar un binario PE manipulado, lo que desencadena el problema y bloquea Shim, lo que resulta en una denegación de servicio.
