Virtuozzo 7 : bind / bind-chroot / bind-devel / bind-libs / etc (VZLSA-2017-0276)

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


Synopsis :

The remote Virtuozzo host is missing a security update.

Description :

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

Red Hat Product Security has rated this update as having a security
impact of Moderate. 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 Berkeley Internet Name Domain (BIND) is an implementation of the
Domain Name System (DNS) protocols. BIND includes a DNS server
(named); a resolver library (routines for applications to use when
interfacing with DNS); and tools for verifying that the DNS server is
operating correctly.

Security Fix(es) :

* A denial of service flaw was found in the way BIND handled query
responses when both DNS64 and RPZ were used. A remote attacker could
use this flaw to make named exit unexpectedly with an assertion
failure or a NULL pointer dereference via a specially crafted DNS
response. (CVE-2017-3135)

Red Hat would like to thank ISC for reporting this issue. Upstream
acknowledges Ramesh Damodaran (Infoblox) and Aliaksandr Shubnik
(Infoblox) as the original reporter.

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.
