Memory leak when failing to parse XDR strings or bytearrays
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)
Affected Packages:
libtirpc
Issue Correction:
Run yum update libtirpc to update your system.
