Statement: Based on technical analysis of this flaw:
On Red Hat Enterprise Linux 6: No looping behaviour was observed. Without the looping behavior, the alloca should be harmless for pretty much all applications because the size argument depends on the size of the generated (outgoing) UDP packet and will be well below default stack sizes. Therefore it is not affected by this flaw.

CVE-2016-4429 [MEDIUM] CVE-2016-4429 glibc: libtirpc: stack (frame) overflow in Sun RPC clntudp_call()
CVE-2016-4429 glibc: libtirpc: stack (frame) overflow in Sun RPC clntudp_call()
A stack frame overflow flaw was found in the glibc's clntudp_call(). A malicious server could use this flaw to flood a connecting client application with ICMP and UDP packets, triggering the stack overflow and resulting in a crash.
clntudp_call() contains an alloca call in a loop, which causes it to consume very large amounts of stack space.
The same faulty code is also present in the libtirpc library.
