3. Description:

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 constructed a response to a query that met certain criteria. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS request packet. (CVE-2016-2776)

Red Hat would like to thank ISC for reporting this issue.

4. Solution:

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

After installing the update, the BIND daemon (named) will be restarted automatically.

5. Bugs fixed (https://bugzilla.redhat.com/):

1378380 - CVE-2016-2776 bind: assertion failure in buffer.c while building responses to a specifically constructed request
