3. Description:

The libtirpc packages contain SunLib's implementation of
transport-independent remote procedure call (TI-RPC) documentation, which
includes a library required by programs in the nfs-utils and rpcbind
packages.

Security Fix(es):

* It was found that due to the way rpcbind uses libtirpc (libntirpc), a
memory leak can occur when parsing specially crafted XDR messages. An
attacker sending thousands of messages to rpcbind could cause its memory
usage to grow without bound, eventually causing it to be terminated by the
OOM killer. (CVE-2017-8779)
