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 flaw was found in the way BIND performed DNSSEC validation. An attacker
able to make BIND (functioning as a DNS resolver with DNSSEC validation
enabled) resolve a name in an attacker-controlled domain could cause named
to exit unexpectedly with an assertion failure. (CVE-2015-4620)
Red Hat would like to thank ISC for reporting this issue.
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.
