nscd: Stack-based buffer overflow in netgroup cache
If the Name Service Cache Daemon's (nscd) fixed size cache is exhausted
by client requests then a subsequent client request for netgroup data
may result in a stack-based buffer overflow. This flaw was introduced
in glibc 2.15 when the cache was added to nscd.
This vulnerability is only present in the nscd binary.
