rpcbind: Fix memory corruption in PMAP_CALLIT code
Use-after-free vulnerability in xprt_set_caller in rpcb_svc_com.c in
rpcbind 0.2.1 and earlier allows remote attackers to cause a denial of
service (daemon crash) via crafted packets, involving a PMAP_CALLIT
code.
The patch comes from
<http://www.openwall.com/lists/oss-security/2015/09/18/7>, and it hasn't
been in rpcbind upstream yet.
