glibc/sunrpc
History
Brad Hubbard ed6b0fe710 Use calloc to allocate xports (BZ #17542) 
If xports is NULL in xprt_register we malloc it but if sock >
_rpc_dtablesize() that memory does not get initialised and may in theory
contain any value. Later we make a conditional jump in svc_getreq_common
based on the uninitialised memory and this caused a general protection
fault in rpc.statd on an older version of glibc but this code has not
changed since that version.

Following is the valgrind warning.
