Linux-Mandrake Security Update Advisory
________________________________________________________________________

Package name: bind
Date: January 29th, 2001
Advisory ID: MDKSA-2001:017

Affected versions: 6.0, 6.1, 7.0, 7.1, 7.2, Corporate Server 1.0.1
________________________________________________________________________

Problem Description:

Four problems exists in all versions of ISC BIND 4.9.x prior to 4.9.8
and 8.2.x prior to 8.2.3 (9.x is not affected). Version 8.2.x contains
a buffer overflow in transaction signature (TSIG) handling code that
can be exploited by an attacker to gain unauthorized privileged access
to the system, allowing execution of arbitrary code. BIND 4 contains
both a buffer overflow in the nslookupComplain() function, as well as
an input validation error in the same function. These two flaws in
BIND 4 can result in a Denial of Service or the execution of arbitrary
code if successfully exploited. Finally, both BIND 4 and BIND 8 suffer
from an information leak in the query processing code that allows a
remote attacker to access the program stack, possibly exposing program
and/or environment variables. This flaw is triggered by sending a
specially formatted query to vulnerable BIND servers.

Linux-Mandrake ships with ISC BIND 8 and is therefore vulnerable to the
first and final vulnerabilities previously mentioned. The first
vulnerability is limited because any access gained exploiting it will
result in restricted access due to the named server running as the user
and group named, not as root.

It is highly recommended that all Linux-Mandrake users upgrade BIND
immediately to the latest 8.2.3 version that fixes these
vulnerabilities.

Please verify the update prior to upgrading to ensure the integrity of
the downloaded package. You can do this with the command:
rpm --checksig package.rpm
You can get the GPG public key of the Linux-Mandrake Security Team at
http://www.linux-mandrake.com/en/security/RPM-GPG-KEYS
If you use MandrakeUpdate, the verification of md5 checksum and GPG
signature is performed automatically for you.

To upgrade automatically, use MandrakeUpdate.

If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm".

You can download the updates directly from one of the mirror sites
listed at:

http://www.linux-mandrake.com/en/ftp.php3.

Updated packages are available in the "updates/[ver]/RPMS/" directory.

For example, if you are looking for an updated RPM package for
Linux-Mandrake 7.2, look for it in "updates/7.2/RPMS/". Updated source
RPMs are available as well, but you generally do not need to download
them.

Please be aware that sometimes it takes the mirrors a few hours to
update.
