Se han publicado los resultados de la prueba de fuzzing de la herramienta ping de OpenBSD, realizada tras el reciente descubrimiento de una vulnerabilidad explotable de forma remota en la herramienta ping proporcionada en FreeBSD. La herramienta ping utilizada en OpenBSD no est\u00e1 sujeta al problema detectado en FreeBSD (la vulnerabilidad est\u00e1 presente en la nueva implementaci\u00f3n de la funci\u00f3n pr_pack(), reescrita por los desarrolladores de FreeBSD en 2019), pero durante la revisi\u00f3n surgi\u00f3 otro error que hab\u00eda pasado desapercibido durante 24 a\u00f1os. Este error provoca un bucle infinito al procesar una respuesta con un campo option de tama\u00f1o cero en un paquete IP. La correcci\u00f3n ya se ha incluido en OpenBSD. El problema no se considera una vulnerabilidad, ya que la pila de red en el n\u00facleo de OpenBSD no permite que tales paquetes lleguen al espacio del usuario.
