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.

A flaw was discovered in the way BIND handled certain DNS requests. A
remote attacker could use this flaw to send a specially-crafted DNS request
packet to BIND, causing it to exit unexpectedly due to a failed assertion.
(CVE-2011-2464)

Users of bind97 on Red Hat Enterprise Linux 5, and bind on Red Hat
Enterprise Linux 6, are advised to upgrade to these updated packages, which
resolve this issue. After installing the update, the BIND daemon (named)
will be restarted automatically.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/kb/docs/DOC-11259

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

718966 - CVE-2011-2464 bind: Specially constructed packet will cause named to exit
