Resumen del impacto: La finalizaci\u00f3n anormal de una aplicaci\u00f3n puede causar una denegaci\u00f3n de servicio. Las aplicaciones que realizan comprobaciones de nombres de certificados (por ejemplo, clientes TLS que comprueban certificados de servidor) pueden intentar leer una direcci\u00f3n de memoria no v\u00e1lida al comparar el nombre esperado con un nombre alternativo de sujeto `otherName` de un certificado X.509.

Tenga en cuenta que la validaci\u00f3n b\u00e1sica de la cadena de certificados (firmas, fechas, ...) no se ve afectada, la denegaci\u00f3n de servicio puede ocurrir solo cuando la aplicaci\u00f3n tambi\u00e9n especifica un nombre DNS, una direcci\u00f3n de correo electr\u00f3nico o una direcci\u00f3n IP esperados. Los servidores TLS rara vez solicitan certificados de cliente, e incluso cuando lo hacen, generalmente no realizan una comprobaci\u00f3n de nombre contra un identificador de referencia (identidad esperada), sino que extraen la identidad presentada despu\u00e9s de comprobar la cadena de certificados.
