Oracle Linux 6 : rpcbind (ELSA-2017-1267)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Oracle Linux host is missing a security update.

Description :

From Red Hat Security Advisory 2017:1267 :

An update for rpcbind is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The rpcbind utility is a server that converts Remote Procedure Call
(RPC) program numbers into universal addresses. It must be running on
the host to be able to make RPC calls on a server on that machine.

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)
