Virtuozzo 7 : bind / bind-chroot / bind-devel / bind-libs / etc (VZLSA-2017-1095)

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 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 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 a query
response containing CNAME or DNAME resource records in an unusual
order. A remote attacker could use this flaw to make named exit
unexpectedly with an assertion failure via a specially crafted DNS
response. (CVE-2017-3137)

* A denial of service flaw was found in the way BIND handled query
requests when using DNS64 with 'break-dnssec yes' option. A remote
attacker could use this flaw to make named exit unexpectedly with an
assertion failure via a specially crafted DNS request. (CVE-2017-3136)

Red Hat would like to thank ISC for reporting these issues. Upstream
acknowledges Oleg Gorokhov (Yandex) as the original reporter of
CVE-2017-3136.

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.
