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(a)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.
<p> 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.rpmŽ. 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 restartŽ
as root after performing the rpm command as shown above. Afterwards,
check for the running daemon using the ps command as `ps auxŽ. The
named process should show a new starting time. Repeat the
`rcnamed restartŽ command if the nameserver shut down too slowly to
release the socket for the new server.

<p> Sparc Platform:
Due to build bottlenecks, the update package for the sparc platform
(SuSE-7.0 distribution) is delayed.
<p>______________________________________________________________________________
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.

SuSE Security Announcement
Package: kdesu
Announcement-ID: SuSE-SA:2001:02
Date:
Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0
Vulnerability Type: local root compromise
Severity (1-10): 3
SuSE default package: yes
Other affected systems: All KDE 1 & KDE 2 systems
Content of this advisory:
1) security vulnerability resolved: kdesu
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
<p> kdesu is a KDE frontend for su(1). When invoked it prompts for the
root password and runs su(1). kdesu itself does not run setuid/setgid.
However when enabling the 'keep password' option it tries to send
the password across process boundaries to kdesud via a UNIX socket.
During this it does not verify the identity of the listener on the other
end. This allows attackers to obtain the root password.
This bug has been fixed in the update packages by checking the ownership
of the socket on the listener side.
Download the update package from locations desribed below and install
the package with the command `rpm -Uhv file.rpm'. The md5sum for each
file is in the line below. You can verify the integrity of the rpm
files using the command
`rpm --checksig --nogpg file.rpm',
independently from the md5 signatures below.

SuSE Security Announcement
Package: glibc (shlibs)
Announcement-ID: SuSE-SA:2001:01
Date: Friday, January 26th, 2001 15:40 MET
Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0
Vulnerability Type: local root compromise
Severity (1-10): 6
SuSE default package: yes
Other affected systems: most Linux/glibc based systems
Content of this advisory:
1) security vulnerability resolved: glibc
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
<p> ld-linux.so.2, the dynamical linker, adds shared libraries to the
memoryspace of a program to be started. Its flexibility allows for
some environment variables to influence the linking process such as
preloading shared libraries as well as defining the path in which
the linker will search for the shared libraries. Special care must
be exercised when runtime-linking setuid- or setgid-binaries:
The runtime-linker must not link against user-specified libraries
since the code therein would then run with the elevated privileges
of the suid binary.
The runtime-linker as used in the SuSE distributions ignores the
content of the critical environment variables if the specified path
begins with a slash ("/"), or if the library file name is not
cached (eg it is contained in a path from /etc/ld.so.conf).
However, Solar Designer has found out that even preloading glibc-
native shared libraries can be dangerous: The code in the user-linked
library is not aware of the fact that the binary runs with suid or
sgid privileges. Using debugging features of the glibc (and possibly
other features) it is possible for a local attacker to overwrite
arbitrary files with the elevated privileges of the suid/sgid binary
executed. This may lead to a local root compromise.
To eliminate these problems, we provide update packages that completely
disregard the LD_* variables upon runtime-linking of a binary that has
an effective uid different from the caller's userid.
<p> Download the update package from locations desribed below and install
the package with the command `rpm -Uhv file.rpm'. The md5sum for each
file is in the line below. You can verify the integrity of the rpm
files using the command
`rpm --checksig --nogpg file.rpm',
independently from the md5 signatures below.
SPECIAL INSTALL INSTRUCTIONS:
==============================
The glibc (the shlibs package) is an intrinsic part of the GNU/Linux
operating system since most binary executables are dependent on
the shared libraries from that package. For this reason, special care
must be taken while updating the shlibs package.
After downloading the binary rpm files, make sure that your system is
idle by bringing it down to Single User Mode (`init 1Ž). If this is not
applicable for operational reasons, then keep your machine as calm as
possible while you perform the update. In particular, make sure that
no shell scripts are running during the update.
Install the package using the command
rpm -Uhv package-rpm-file
Do _NOT_ interrupt the operation of the rpm command!
After the installation, execute the commands
ldconfig # alternatively, use SuSEconfig
/sbin/init u # will restart init
At this point, the update is done.
On low-memory machines a reboot is advisable to free the memory that
is used by the old memory-mapped libraries.
<p> Note 1:
The upcoming SuSE-7.1 distribution is based on glibc-2.2. This
distribution is not affected by the security problems in glibc as
discussed in security forums.
Note 2:
The source rpm for the shlibs package is called "libc*.rpm".
Multiple binary rpm packages are being generated from this source
rpm package. These include: localedb, nssv1, shlibs, timezone.
To get a fix for the runtime-linker related security issue (topic
of this announcement), it is only necessary to update the shlibs
binary rpm package.

2) Pending vulnerabilities in SuSE Distributions and Workarounds:
This announcement is followed by a sequence of more announcements
to address the ongoing security problems as discussed in public
security forums. In particular, there are temporary file races in
multiple packages (we collect and address them in a single
announcement to keep the noise low), format string bugs, as well
as a man-in-the-middle attack in the kdesu program and a single-byte
buffer overflow. The next announcenemts will contain more information
on these topics.
Please stay tuned.
