sunrpc: Avoid use-after-free read access in clntudp_call [BZ #21115]
After commit bc779a1a5b3035133024b21e2f339fe4219fb11c (CVE-2016-4429: sunrpc: Do not use alloca in clntudp_call [BZ #20112]), ancillary data is stored on the heap, but it is accessed after it has been freed. The test case must be run under a heap debugger such as valgrind to observe the invalid access. A malloc implementation which immediately calls munmap on free would catch this bug as well.
