Virtuozzo 7 : rpcbind (VZLSA-2017-1262)

High Nessus Plugin ID 101466


The remote Virtuozzo host is missing a security update.


An update for rpcbind is now available for Red Hat Enterprise Linux 7.

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)

Note that Tenable Network Security has attempted to extract the preceding description block directly from the corresponding Red Hat security advisory. Virtuozzo provides no description for VZLSA advisories. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected rpcbind package.
