Publicado<\/a><\/noindex> actualizaci\u00f3n del sistema de almacenamiento en cach\u00e9 en la memoria Memcached 1.6.2<\/a><\/noindex>, en el que se corrige vulnerabilidad<\/a><\/noindex>, que permite iniciar un fallo en el flujo de trabajo mediante el env\u00edo de una solicitud especialmente dise\u00f1ada. La vulnerabilidad se manifiesta a partir de la versi\u00f3n 1.6.0. Como una soluci\u00f3n temporal, se puede desactivar el protocolo binario para solicitudes externas ejecutando con la opci\u00f3n \u00ab-B ascii\u00bb.<\/p>\n

El problema es causado por un error en el c\u00f3digo<\/a><\/noindex> el an\u00e1lisis del encabezado del protocolo binario relacionado con la definici\u00f3n incorrecta del tama\u00f1o de los datos copiados en el b\u00fafer al llamar a la funci\u00f3n memcpy (el tama\u00f1o se determina en funci\u00f3n del par\u00e1metro especificado en el encabezado de la solicitud). A trav\u00e9s de manipulaciones con el valor del par\u00e1metro en el encabezado del protocolo binario, un atacante que puede conectarse al puerto de red de Memcached puede provocar un desbordamiento de b\u00fafer, lo que lleva al fallo del proceso de trabajo.<\/p>\n
