---------------------------------------------------------------------
1. Topic:
Version 9 of the bind name prior to version 9.2.1 contain a denial of
service vulnerability.
2. Relevant releases/architectures:
Red Hat Linux 7.1 - alpha, i386, ia64
Red Hat Linux 7.2 - i386, ia64
Red Hat Linux 7.3 - i386
3. Problem description:
BIND (Berkeley Internet Name Domain) is an implementation of the DNS
(Domain Name System) protocols. Versions of BIND 9 prior to 9.2.1 have a b=
ug
that causes certain requests to the BIND name server (named) to fail an
internal consistency check, causing the name server to stop responding to
requests. This can be used by a remote attacker to cause a denial of
service (DOS) attack against name servers.
Red Hat Linux 7.1, 7.2 and 7.3 shipped with versions of BIND vulnerable to
this issue. All users of BIND are advised to upgrade to the errata
packages containing BIND 9.2.1 which is not vulnerable to this issue.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
