CentOS 5 / 6 / 7 : bind (CESA-2016:0459)
Medium Nessus Plugin ID 89970
SynopsisThe remote CentOS host is missing one or more security updates.
DescriptionUpdated bind packages that fix two security issues are now available for Red Hat Enterprise Linux 5, 6, and 7.
Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links 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.
A denial of service flaw was found in the way BIND parsed signature records for DNAME records. By sending a specially crafted query, a remote attacker could use this flaw to cause named to crash.
A denial of service flaw was found in the way BIND processed certain control channel input. A remote attacker able to send a malformed packet to the control channel could use this flaw to cause named to crash. (CVE-2016-1285)
Red Hat would like to thank ISC for reporting these issues.
All bind users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the update, the BIND daemon (named) will be restarted automatically.
SolutionUpdate the affected bind packages.
