+    sunrpc: Do not use alloca in clntudp_call
+    
+    CVE-2016-4429:
+    The call is technically in a loop, and under certain circumstances
+    (which are quite difficult to reproduce in a test case), alloca
+    can be invoked repeatedly during a single call to clntudp_call.
+    As a result, the available stack space can be exhausted (even
+    though individual alloca sizes are bounded implicitly by what
+    can fit into a UDP packet, as a side effect of the earlier
+    successful send operation).
+    
+    From GNU libc:
