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.
