High Nessus Plugin ID 100641
SynopsisThe remote Amazon Linux AMI host is missing a security update.
DescriptionMemory 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)
SolutionRun 'yum update libtirpc' to update your system.
