CentOS Errata and Security Advisory CESA-2008:0533

ISC BIND (Berkeley Internet Name Domain) is an implementation of the DNS
(Domain Name System) protocols.

The DNS protocol protects against spoofing attacks by requiring an attacker
to predict both the DNS transaction ID and UDP source port of a request. In
recent years, a number of papers have found problems with DNS
implementations which make it easier for an attacker to perform DNS
cache-poisoning attacks.

Previous versions of BIND did not use randomized UDP source ports. If an
attacker was able to predict the random DNS transaction ID, this could make
DNS cache-poisoning attacks easier. In order to provide more resilience,
BIND has been updated to use a range of random UDP source ports.
(CVE-2008-1447)

Note: This errata also updates SELinux policy on Red Hat Enterprise Linux 4
and 5 to allow BIND to use random UDP source ports.

Users of BIND are advised to upgrade to these updated packages, which
contain a backported patch to add this functionality.

Red Hat would like to thank Dan Kaminsky for reporting this issue.

Affected packages:
bind
bind-chroot
bind-devel
bind-libbind-devel
bind-libs
bind-sdb
bind-utils
caching-nameserver
selinux-policy
selinux-policy-devel
selinux-policy-mls
selinux-policy-strict
selinux-policy-targeted
selinux-policy-targeted-sources
