nscd: netgroup cache may terminate daemon on memory allocation failure
The Name Service Cache Daemon's (nscd) netgroup cache uses xmalloc or
xrealloc and these functions may terminate the process due to a memory
allocation failure resulting in a denial of service to the clients. The
flaw was introduced in glibc 2.15 when the cache was added to nscd.
This vulnerability is only present in the nscd binary.
