SuSE Security Announcement
Package: bind8
Announcement-ID: SuSE-SA:2001:03
Date: Tuesday, January 30th, 2000 23:40 MEST
Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0, 7.1
Vulnerability Type: remote root compromise
Severity (1-10): 9
SuSE default package: no
Other affected systems: all systems using bind, versions before
8.2.3-REL
Content of this advisory:
1) security vulnerability resolved: bind8
problem description, discussion, solution and upgrade information
2) pending vulnerabilities, solutions, workarounds
3) standard appendix (further information)
______________________________________________________________________________
1) problem description, brief discussion, solution, upgrade
information
bind-8.x in all versions of the SuSE distributions contain a bug
in the transaction signature handling code that can allow to
remotely over- flow a buffer and thereby execute arbitrary code
as the user running the nameserver (this is user named by default
on SuSE systems). In addition to this bug, another problem
allows for a remote attacker to collect information about the
running bind process (this has been found by Claudio Musmarra
<a9605121@unet.univie.ac.at>). For more information on these
bugs, please visit the CERT webpage at
http://www.cert.org/advisories/CA-2001-02.html and the bind bugs
webpage at http://www.isc.org/products/BIND/bind-security.html .
The problem is existent in the upcoming SuSE distribution 7.1 that
will be available by February 10th in the CD/DVD version.
There exists no reasonable method to circumvent the problems
other than to update the package as described below.
Please choose the update package for your distribution from the
URLs listed below and download the necessary rpm files. Then,
install the package using the command `rpm -Uhv file.rpm´. rpm
packages have an internal md5 checksum that protects against file
corruption. You can verify this checksum using the command
(independently from the md5 signatures below)
`rpm --checksig --nogpg file.rpm',
The md5 sums under each package are to prove the package authenticity,
independently from the md5 checksums in the rpm package format.
SPECIAL INSTALL INSTRUCTIONS:
==============================
If you run a bind8 nameserver on your system, please update the package
immediately. In order for the updated package to become active, the
nameserver process "named" needs to be restarted. Do this using the
command
`rcnamed restart´
as root after performing the rpm command as shown above. Afterwards,
check for the running daemon using the ps command as `ps aux´. The
named process should show a new starting time. Repeat the
`rcnamed restart´ command if the nameserver shut down too slowly to
release the socket for the new server.

______________________________________________________________________________
2) Pending vulnerabilities in SuSE Distributions and Workarounds:
SuSE distributions contain the bind nameserver in Version 4 as
well. bind-4.x in the currently used version has
security-related bugs, some of which are similar to the ones in
the 8.x versions. We will provide update packages as well as an
announcement for the bind
(not bind8) package shortly, along with an own announcement.
