nscd: Null pointer crashes after notfound response

If the Name Service Cache Daemons (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.

Weakness

The product dereferences a pointer that it expects to be valid but is NULL.
