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 processed certain malformed Address Prefix List (APL) records. A remote, authenticated attacker could use this flaw to cause named to crash. (CVE-2015-8704)
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.
