nscd: netgroup cache assumes NSS callback uses in-buffer strings
The Name Service Cache Daemon's (nscd) netgroup cache can corrupt memory
when the NSS callback does not store all strings in the provided buffer.
The flaw was introduced in glibc 2.15 when the cache was added to nscd.
This vulnerability is only present in the nscd binary.
