Title:RedHat Security Advisory RHSA-2012:0717
The remote host is missing updates announced in
advisory RHSA-2012:0717.

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)
tools for verifying that the DNS server is operating correctly.

A flaw was found in the way BIND handled zero length resource data records.
A malicious owner of a DNS domain could use this flaw to create
specially-crafted DNS resource records that would cause a recursive
resolver or secondary server to crash or, possibly, disclose portions of
its memory. (CVE-2012-1667)

A flaw was found in the way BIND handled the updating of cached name server
(NS) resource records. A malicious owner of a DNS domain could use this
flaw to keep the domain resolvable by the BIND server even after the
delegation was removed from the parent DNS zone. With this update, BIND
limits the time-to-live of the replacement record to that of the
time-to-live of the record being replaced. (CVE-2012-1033)

Users of bind97 are advised to upgrade to these updated packages, which
correct these issues. After installing the update, the BIND daemon (named)
will be restarted automatically.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date

Risk factor : High
