The remote Red Hat host is missing one or more security updates.
Updated bind packages that fix a security issue and a bug are now
available for Red Hat Enterprise Linux 4.
This update has been rated as having important security impact by the
Red Hat Security Response Team.
The Berkeley Internet Name Domain (BIND) is an implementation of the
Domain Name System (DNS) protocols. BIND includes a DNS server
a resolver library (routines for applications to use when
interfacing with DNS)
and tools for verifying that the DNS server is
A flaw was found in the way BIND handles dynamic update message
packets containing the 'ANY' record type. A remote attacker could use
this flaw to send a specially crafted dynamic update packet that could
cause named to exit with an assertion failure. (CVE-2009-0696)
Note: even if named is not configured for dynamic updates, receiving
such a specially crafted dynamic update packet could still cause named
to exit unexpectedly.
This update also fixes the following bug :
* when running on a system receiving a large number of (greater than
4,000) DNS requests per second, the named DNS nameserver became
unresponsive, and the named service had to be restarted in order for
it to continue serving requests. This was caused by a deadlock
occurring between two threads that led to the inability of named to
continue to service requests. This deadlock has been resolved with
these updated packages so that named no longer becomes unresponsive
under heavy load. (BZ#512668)
All BIND users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues. After installing
the update, the BIND daemon (named) will be restarted automatically.
