Virtuozzo 6 : bind / bind-chroot / bind-devel / bind-libs / etc (VZLSA-2017-1105)
Medium Nessus Plugin ID 101456
SynopsisThe remote Virtuozzo host is missing a security update.
DescriptionAn update for bind 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 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.
