Descriptions

nscd: Null pointer crashes after notfound response

If the Name Service Cache Daemon's (nscd) cache fails to add a not-found
netgroup response to the cache, the client request can result in a null
pointer dereference. This flaw was introduced in glibc 2.15 when the
cache was added to nscd.

This vulnerability is only present in the nscd binary.

nscd: el puntero nulo falla después de una respuesta no encontrada Si el caché del daemon de caché del servicio de nombres (nscd) no logra agregar una respuesta de grupo de red no encontrado al caché, la solicitud del cliente puede resultar en una desreferencia del puntero nulo. Esta falla se introdujo en glibc 2.15 cuando se agregó el caché a nscd. Esta vulnerabilidad sólo está presente en el binario nscd.

A flaw was found in the glibc netgroup cache. After a failed cache insertion, addgetnetgrentX tries to send the non-existing response after the not-found header. This can lead to a null pointer dereference that causes a crash or exit.
