Descriptions

A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash.

Se encontró una falla en glibc. Cuando se llama a la función getaddrinfo con la familia de direcciones AF_UNSPEC y el sistema está configurado con el modo no-aaaa a través de /etc/resolv.conf, una respuesta DNS a través de TCP de más de 2048 bytes puede potencialmente revelar el contenido de la pila de memoria a través de los datos de la dirección devuelta por la función, y puede provocar un crash.

*Credits: This issue was discovered by Florian Weimer (Red Hat).
