CentOS Errata and Security Advisory CESA-2015:1705
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 certain malformed
DNSSEC keys. A remote attacker could use this flaw to send a specially
crafted DNS query (for example, a query requiring a response from a zone
containing a deliberately malformed key) that would cause named functioning
as a validating resolver to crash. (CVE-2015-5722)
Red Hat would like to thank ISC for reporting this issue. Upstream
acknowledges Hanno BΓΆck as the original reporter.
All bind users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing the
update, the BIND daemon (named) will be restarted automatically.
