1) problem description, brief discussion, solution, upgrade information
The Dynamic Host Configuration Protocol (DHCP) server is used to
configure clients that dynamically connect to a network (WLAN
hotspots, customer networks, ...).
The CERT informed us about a buffer overflow in the logging code of the
server that can be triggered by a malicious client by supplying multiple
hostnames. The hostname strings are concatenated and copied in a
fixed size buffer without checking the buffer bounds.
Other possible buffer overflow conditions exist in using vsprintf()
instead of vsnprintf(). This behavior can be configured during compile-
time. The dhcp/dhcp-server package coming with SUSE LINUX used the
vulnerable vsprintf() function.
Since SuSE Linux 8.1/SuSE Linux Enterprise Server 8 the DHCP server runs
as non-root user in a chroot jail. This setup limits the impact of a
successful attack.
There is no temporary workaround known.
Please download the update package for your distribution and verify its
integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command "rpm -Fhv file.rpm" to apply
the update.
Our maintenance customers are being notified individually. The packages
are being offered to install from the maintenance web.

- icecast
The icecast service is vulnerable to a remote denial-of-service
attack. Update packages will be available soon.
- sitecopy
The sitecopy package includes a vulnerable version of the
neon library (CAN-2004-0179, CAN-2004-0398). Update packages will be
available soon.
- cadaver
The cadaver package includes a vulnerable version of the
neon library (CAN-2004-0179, CAN-2004-0398). Update packages will be
available soon.
- OpenOffice_org
The OpenOffice_org package includes a vulnerable version
of the neon library (CAN-2004-0179, CAN-2004-0398). Update packages
will be available soon.
- tripwire
A format string bug in tripwire can be exploited locally
to gain root permissions. Update packages will be available soon.
- postgresql
A buffer overflow in psqlODBC could be exploited to crash the
application using it. E.g. a PHP script that uses ODBC to access a
PostgreSQL database can be utilized to crash the surrounding Apache
web-server. Other parts of PostgreSQL are not affected.
Update packages will be available soon.
- lha
Minor security fix for a buffer overflow while handling command
line options. This buffer overflow could be exploited in conjunction
with other mechanisms to gain higher privileges or access the system
remotely.
Packages are available now.
- XDM/XFree86
This update resolves random listening to ports by XDM
that allows to connect via the XDMCP. SUSE LINUX 9.1
is affected only.
New packages are currently being tested and will be
available soon.
- mod_proxy
A buffer overflow can be triggered by malicious remote
servers that return a negative Content-Length value.
This vulnerability can be used to execute commands remotely
New packages are currently being tested and will be
available soon.

3) standard appendix: authenticity verification, additional information
- Package authenticity verification:
SUSE update packages are available on many mirror ftp servers all over
the world. While this service is being considered valuable and important
to the free and open source software community, many users wish to be
sure about the origin of the package and its content before installing
the package. There are two verification methods that can be used
independently from each other to prove the authenticity of a downloaded
file or rpm package:
1) md5sums as provided in the (cryptographically signed) announcement.
2) using the internal gpg signatures of the rpm package.
1) execute the command
md5sum <name-of-the-file.rpm>
after you downloaded the file from a SUSE ftp server or its mirrors.
Then, compare the resulting md5sum with the one that is listed in the
announcement. Since the announcement containing the checksums is
cryptographically signed (usually using the key security(a)suse.de)
the checksums show proof of the authenticity of the package.
We disrecommend to subscribe to security lists which cause the
email message containing the announcement to be modified so that
the signature does not match after transport through the mailing
list software.
Downsides: You must be able to verify the authenticity of the
announcement in the first place. If RPM packages are being rebuilt
and a new version of a package is published on the ftp server, all
md5 sums for the files are useless.
2) rpm package signatures provide an easy way to verify the authenticity
of an rpm package. Use the command
rpm -v --checksig <file.rpm>
to verify the signature of the package, where <file.rpm> is the
filename of the rpm package that you have downloaded. Of course,
package authenticity verification can only target an un-installed rpm
package file.
Prerequisites:
a) gpg is installed
b) The package is signed using a certain key. The public part of this
key must be installed by the gpg program in the directory
~/.gnupg/ under the user's home directory who performs the
signature verification (usually root). You can import the key
that is used by SUSE in rpm packages for SUSE LINUX by saving
this announcement to a file ("announcement.txt") and
running the command (do "su -" to be root):
gpg --batch; gpg < announcement.txt | gpg --import
SUSE LINUX distributions version 7.1 and thereafter install the
key "build(a)suse.de" upon installation or upgrade, provided that
the package gpg is installed. The file containing the public key
is placed at the top-level directory of the first CD (pubring.gpg)
and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de .
- SUSE runs two security mailing lists to which any interested party may

Subversion is a version control system like the well known CVS.
The subversion code is vulnerable to a remotely exploitable buffer
overflow on the heap. The bug appears before any authentication took
place. An attacker is able to execute arbitray code by abusing this
vulnerability.
There is no temporary workaround known.
Please download the update package for your distribution and verify its
integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command "rpm -Fhv file.rpm" to apply
the update.
Our maintenance customers are being notified individually. The packages
are being offered to install from the maintenance web.

PostgreSQL database can be utilized to crash the surrounding Apache
web-server. Other parts of PostgreSQL are not affected.
Update packages will be available soon.
- lha
Minor security fix for a buffer overflow while handling command
line options. This buffer overflow could be exploited in conjunction
with other mechanisms to gain higher privileges or access the system
remotely.
- XDM/XFree86
This update resolves random listening to ports by XDM
that allows to connect via the XDMCP. SUSE LINUX 9.1
is affected only.
New packages are currently being tested and will be
available soon.
- mod_proxy
A buffer overflow can be triggered by malicious remote
servers that return a negative Content-Length value.
This vulnerability can be used to execute commands remotely
New packages are currently being tested and will be
available soon.

3) standard appendix: authenticity verification, additional information
- Package authenticity verification:
SUSE update packages are available on many mirror ftp servers all over
the world. While this service is being considered valuable and important
to the free and open source software community, many users wish to be
sure about the origin of the package and its content before installing
the package. There are two verification methods that can be used
independently from each other to prove the authenticity of a downloaded
file or rpm package:
1) md5sums as provided in the (cryptographically signed) announcement.
2) using the internal gpg signatures of the rpm package.
1) execute the command
md5sum <name-of-the-file.rpm>
after you downloaded the file from a SUSE ftp server or its mirrors.
Then, compare the resulting md5sum with the one that is listed in the
announcement. Since the announcement containing the checksums is
cryptographically signed (usually using the key security(a)suse.de)
the checksums show proof of the authenticity of the package.
We disrecommend to subscribe to security lists which cause the
email message containing the announcement to be modified so that
the signature does not match after transport through the mailing
list software.
Downsides: You must be able to verify the authenticity of the
announcement in the first place. If RPM packages are being rebuilt
and a new version of a package is published on the ftp server, all
md5 sums for the files are useless.
2) rpm package signatures provide an easy way to verify the authenticity
of an rpm package. Use the command
rpm -v --checksig <file.rpm>
to verify the signature of the package, where <file.rpm> is the
filename of the rpm package that you have downloaded. Of course,
package authenticity verification can only target an un-installed rpm
package file.
Prerequisites:
a) gpg is installed
b) The package is signed using a certain key. The public part of this
key must be installed by the gpg program in the directory
~/.gnupg/ under the user's home directory who performs the
signature verification (usually root). You can import the key
that is used by SUSE in rpm packages for SUSE Linux by saving
this announcement to a file ("announcement.txt") and
running the command (do "su -" to be root):
gpg --batch; gpg < announcement.txt | gpg --import
SUSE Linux distributions version 7.1 and thereafter install the
key "build(a)suse.de" upon installation or upgrade, provided that
the package gpg is installed. The file containing the public key
is placed at the top-level directory of the first CD (pubring.gpg)
and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de .
- SUSE runs two security mailing lists to which any interested party may
subscribe:
suse-security(a)suse.com
- general/linux/SUSE security discussion.
All SUSE security announcements are sent to this list.
To subscribe, send an email to
<suse-security-subscribe(a)suse.com>.

Dear suse-security-announce subscribers and SUSE LINUX users,
having provided security-relevant fixes for version 8.0 of our home user
product, SUSE Linux, for two years, we would like to inform you that SUSE
Linux 8.0 will be discontinued for all architectures. Vulnerabilities
found after June 30th 2004 will not be fixed any more for SUSE Linux
8.0.
By consequence, the SUSE Linux 8.0 distribution directories on our ftp
server ftp.suse.com will be moved to the /pub/suse/discontinued/ directory
tree structure to free space after the recent availability of the new SUSE
LINUX 9.1 ftp version; the 8.0 directories in the update trees will follow
later in July/August 2004, as soon as all updates have been published.
The discontinuation of SUSE Linux 8.0 enables us to focus on the SUSE
LINUX distributions of a newer release date to ensure that our customers
can continuously take advantage of the quality that they are used to with
SUSE LINUX products.
This announcement holds true for SuSE Linux 8.0 only. As usual, SUSE
will continue to provide update packages for the following home users
distributions:
SuSE Linux 8.1
SuSE Linux 8.2
SUSE LINUX 9.0
and
SUSE LINUX 9.1
for a two-year period after the release of the respective distribution.
Please note that the maintenance cycles of SUSE LINUX Enterprise Server
products and products based on the SUSE LINUX Enterprise Server operating
system are not affected by this announcement. To learn more about SUSE
LINUX business products, please visit
http://www.suse.com/us/business/products/.
If you have any questions regarding this announcement, please do
not hesitate to contact SUSE security at <security(a)suse.de>.
Best regards,
Roman Drahtmüller,
SUSE Security.

1) problem description, brief discussion, solution, upgrade information
The Linux kernel is vulnerable to a local denial-of-service attack.
By using a C program it is possible to trigger a floating point
exception that puts the kernel into an unusable state.
To execute this attack a malicious user needs shell access to the
victim's machine.
The severity of this bug is considered low because local denial-of-
service attacks are hard to prevent in general.
Additionally the bug is limited to x86 and x86_64 architecture.
SPECIAL INSTALL INSTRUCTIONS:
==============================
The following paragraphs will guide you through the installation
process in a step-by-step fashion. The character sequence "****"
marks the beginning of a new paragraph. In some cases, the steps
outlined in a particular paragraph may or may not be applicable
to your situation.
Therefore, please make sure to read through all of the steps below
before attempting any of these procedures.
All of the commands that need to be executed are required to be
run as the superuser (root). Each step relies on the steps before
it to complete successfully.
Note: The update packages for the SuSE Linux Enterprise Server 7
(SLES7) are being tested at the moment and will be published as soon
as possible.
**** Step 1: Determine the needed kernel type
Please use the following command to find the kernel type that is
installed on your system:
rpm -qf /boot/vmlinuz
Following are the possible kernel types (disregard the version and
build number following the name separated by the "-" character)
k_deflt # default kernel, good for most systems.
k_i386 # kernel for older processors and chipsets
k_athlon # kernel made specifically for AMD Athlon(tm) family processors
k_psmp # kernel for Pentium-I dual processor systems
k_smp # kernel for SMP systems (Pentium-II and above)
k_smp4G # kernel for SMP systems which supports a maximum of 4G of RAM
kernel-64k-pagesize
kernel-bigsmp
kernel-default
kernel-smp
**** Step 2: Download the package for your system
Please download the kernel RPM package for your distribution with the
name as indicated by Step 1. The list of all kernel rpm packages is
appended below. Note: The kernel-source package does not
contain a binary kernel in bootable form. Instead, it contains the
sources that the binary kernel rpm packages are created from. It can be
used by administrators who have decided to build their own kernel.
Since the kernel-source.rpm is an installable (compiled) package that
contains sources for the linux kernel, it is not the source RPM for
the kernel RPM binary packages.
The kernel RPM binary packages for the distributions can be found at the
locations below ftp://ftp.suse.com/pub/suse/i386/update/.
8.0/images/
8.1/rpm/i586
8.2/rpm/i586
9.0/rpm/i586
9.1/rpm/i586
After downloading the kernel RPM package for your system, you should
verify the authenticity of the kernel rpm package using the methods as
listed in section 3) of each SUSE Security Announcement.
**** Step 3: Installing your kernel rpm package
Install the rpm package that you have downloaded in Steps 3 or 4 with
the command
rpm -Uhv --nodeps --force <K_FILE.RPM>
where <K_FILE.RPM> is the name of the rpm package that you downloaded.
Warning: After performing this step, your system will likely not be
able to boot if the following steps have not been fully
followed.
If you run SUSE LINUX 8.1 and haven't applied the kernel update
(SUSE-SA:2003:034), AND you are using the freeswan package, you also
need to update the freeswan rpm as a dependency as offered
by YOU (YaST Online Update). The package can be downloaded from
ftp://ftp.suse.com/pub/suse/i386/update/8.1/rpm/i586/
**** Step 4: configuring and creating the initrd
The initrd is a ramdisk that is loaded into the memory of your
system together with the kernel boot image by the bootloader. The
kernel uses the content of this ramdisk to execute commands that must
be run before the kernel can mount its actual root filesystem. It is
usually used to initialize SCSI drivers or NIC drivers for diskless
operation.
The variable INITRD_MODULES in /etc/sysconfig/kernel determines
which kernel modules will be loaded in the initrd before the kernel
has mounted its actual root filesystem. The variable should contain
your SCSI adapter (if any) or filesystem driver modules.
With the installation of the new kernel, the initrd has to be
re-packed with the update kernel modules. Please run the command
mk_initrd
as root to create a new init ramdisk (initrd) for your system.
On SuSE Linux 8.1 and later, this is done automatically when the
RPM is installed.
**** Step 5: bootloader
If you run a SUSE LINUX 8.x, SLES8, or SUSE LINUX 9.x system, there
are two options:
Depending on your software configuration, you have either the lilo
bootloader or the grub bootloader installed and initialized on your
system.
The grub bootloader does not require any further actions to be
performed after the new kernel images have been moved in place by the
rpm Update command.
If you have a lilo bootloader installed and initialized, then the lilo
program must be run as root. Use the command
grep LOADER_TYPE /etc/sysconfig/bootloader
to find out which boot loader is configured. If it is lilo, then you
must run the lilo command as root. If grub is listed, then your system
does not require any bootloader initialization.
Warning: An improperly installed bootloader may render your system
unbootable.
**** Step 6: reboot
If all of the steps above have been successfully completed on your
system, then the new kernel including the kernel modules and the
initrd should be ready to boot. The system needs to be rebooted for
the changes to become active. Please make sure that all steps have
completed, then reboot using the command
shutdown -r now
or
init 6
Your system should now shut down and reboot with the new kernel.
There is no workaround known.
Please download the update package for your distribution and verify its
integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command "rpm -Fhv file.rpm" to apply
the update.
Our maintenance customers are being notified individually. The packages
are being offered to install from the maintenance web.

3) standard appendix: authenticity verification, additional information
- Package authenticity verification:
SUSE update packages are available on many mirror ftp servers around
the world. While this service is considered valuable and important
to the free and open source software community, many users wish to be
certain as to be the origin of the package and its content before
installing the package. There are two independent verification methods
that can be used to prove the authenticity of a downloaded file or
rpm package:
1) md5sums as provided in the (cryptographically signed) announcement.
2) using the internal gpg signatures of the rpm package.
1) execute the command
md5sum <name-of-the-file.rpm>
after you have downloaded the file from a SUSE ftp server or its
mirrors. Then, compare the resulting md5sum with the one that is
listed in the announcement. Since the announcement containing the
checksums is cryptographically signed (usually using the key
security(a)suse.de) the checksums offer proof of the authenticity
of the package.
We recommend against subscribing to security lists which cause the
email message containing the announcement to be modified so that
the signature does not match after transport through the mailing
list software.
Downsides: You must be able to verify the authenticity of the
announcement in the first place. If RPM packages are being rebuilt
and a new version of a package is published on the ftp server, all
md5 sums for the files are useless.
2) rpm package signatures provide an easy way to verify the authenticity
of an rpm package. Use the command
rpm -v --checksig <file.rpm>
to verify the signature of the package, where <file.rpm> is the
filename of the rpm package that you have downloaded. Of course,
package authenticity verification can only target an un-installed rpm
package file.
Prerequisites:
a) gpg is installed
b) The package is signed using a certain key. The public part of this
key must be installed by the gpg program in the directory
~/.gnupg/ under the user's home directory who performs the
signature verification (usually root). You can import the key
that is used by SUSE in rpm packages for SUSE Linux by saving
this announcement to a file ("announcement.txt") and

2) Pending vulnerabilities in SUSE Distributions and Workarounds:
- icecast
The icecast service is vulnerable to a remote denial-of-service
attack. Update packages will be available soon.
- sitecopy
The sitecopy package includes a vulnerable version of the
neon library (CAN-2004-0179, CAN-2004-0398). Update packages will be
available soon.
- cadaver
The cadaver package includes a vulnerable version of the
neon library (CAN-2004-0179, CAN-2004-0398). Update packages will be
available soon.
- tla
The tla package includes a vulnerable version of the
neon library (CAN-2004-0179, CAN-2004-0398). Update packages are
available on our FTP servers.
- OpenOffice_org
The OpenOffice_org package includes a vulnerable version
of the neon library (CAN-2004-0179, CAN-2004-0398). Update packages
will be available soon.
- tripwire
A format string bug in tripwire can be exploited locally
to gain root permissions. Update packages will be available soon.
- postgresql
A buffer overflow in psqlODBC could be exploited to crash the
application using it. E.g. a PHP script that uses ODBC to access a
PostgreSQL database can be utilized to crash the surrounding Apache
web-server. Other parts of PostgreSQL are not affected.
Update packages will be available soon.
- lha
Minor security fix for a buffer overflow while handling command
line options. This buffer overflow could be exploited in conjunction
with other mechanisms to gain higher privileges or access the system
remotely.
______________________________________________________________________________
3) standard appendix: authenticity verification, additional information
- Package authenticity verification:
SUSE update packages are available on many mirror ftp servers all over
the world. While this service is being considered valuable and important
to the free and open source software community, many users wish to be
sure about the origin of the package and its content before installing
the package. There are two verification methods that can be used
independently from each other to prove the authenticity of a downloaded
file or rpm package:
1) md5sums as provided in the (cryptographically signed) announcement.
2) using the internal gpg signatures of the rpm package.
1) execute the command
md5sum <name-of-the-file.rpm>
after you downloaded the file from a SUSE ftp server or its mirrors.
Then, compare the resulting md5sum with the one that is listed in the
announcement. Since the announcement containing the checksums is
cryptographically signed (usually using the key security(a)suse.de)
the checksums show proof of the authenticity of the package.
We disrecommend to subscribe to security lists which cause the
email message containing the announcement to be modified so that
the signature does not match after transport through the mailing
list software.
Downsides: You must be able to verify the authenticity of the
announcement in the first place. If RPM packages are being rebuilt
and a new version of a package is published on the ftp server, all
md5 sums for the files are useless.
2) rpm package signatures provide an easy way to verify the authenticity
of an rpm package. Use the command
rpm -v --checksig <file.rpm>
to verify the signature of the package, where <file.rpm> is the
filename of the rpm package that you have downloaded. Of course,
package authenticity verification can only target an un-installed rpm
package file.
Prerequisites:
a) gpg is installed
b) The package is signed using a certain key. The public part of this
key must be installed by the gpg program in the directory
~/.gnupg/ under the user's home directory who performs the
signature verification (usually root). You can import the key
that is used by SUSE in rpm packages for SUSE Linux by saving
this announcement to a file ("announcement.txt") and
running the command (do "su -" to be root):
gpg --batch; gpg < announcement.txt | gpg --import
SUSE Linux distributions version 7.1 and thereafter install the
key "build(a)suse.de" upon installation or upgrade, provided that
the package gpg is installed. The file containing the public key
is placed at the top-level directory of the first CD (pubring.gpg)
and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de .
- SUSE runs two security mailing lists to which any interested party may
subscribe:

1) problem description, brief discussion, solution, upgrade information
The Concurrent Versions System (CVS) offers tools which allow developers
to share and maintain large software projects.
Various remotely exploitable conditions have been found during a
source code review of CVS done by Stefan Esser and Sebastian Krahmer
(SuSE Security-Team).
These bugs allow remote attackers to execute arbitrary code as the user
the CVS server runs as. Since there is no easy workaround we strongly
recommend to update the cvs package.
The update packages fix vulnerabilities which have been assigned the
CAN numbers CAN-2004-0416, CAN-2004-0417 and CAN-2004-0418.
The cvs packages shipped by SUSE (as well as our recent updates for CVS)
are not vulnerable to CAN-2004-0414.
Please download the update package for your distribution and verify its
integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command "rpm -Fhv file.rpm" to apply
the update.
Our maintenance customers are being notified individually. The packages
are being offered to install from the maintenance web.

2) Pending vulnerabilities in SUSE Distributions and Workarounds:
- icecast
The icecast service is vulnerable to a remote denial-of-service
attack. Update packages will be available soon.
- sitecopy
The sitecopy package includes a vulnerable version of the
neon library (CAN-2004-0179, CAN-2004-0398). Update packages will be
available soon.
- cadaver
The cadaver package includes a vulnerable version of the
neon library (CAN-2004-0179, CAN-2004-0398). Update packages will be
available soon.
- tla
The tla package includes a vulnerable version of the
neon library (CAN-2004-0179, CAN-2004-0398). Update packages will be
available soon.
- OpenOffice_org
The OpenOffice_org package includes a vulnerable version
of the neon library (CAN-2004-0179, CAN-2004-0398). Update packages
will be available soon.
- tripwire
A format string bug in tripwire can be exploited locally
to gain root permissions. Update packages will be available soon.
- postgresql
A buffer overflow in psqlODBC could be exploited to crash the
application using it. E.g. a PHP script that uses ODBC to access a
PostgreSQL database can be utilized to crash the surrounding Apache
webserver. Other parts of PostgreSQL are not affected.
Update packages will be available soon.
- lha
Minor security fix for a buffer overflow while handling command
line options. This buffer overflow could be exploited in conjunction
with other mechanisms to gain higher privileges or access the system
remotely.
- apache/mod_ssl
A buffer overflow in a uuencode function of mod_ssl has been fixed as
well as various minor bugs (CAN-2003-0987, CAN-2003-0020, CAN-2004-0174
and CAN-2003-0993). New packages are available on our ftp servers.

3) standard appendix: authenticity verification, additional information
- Package authenticity verification:
SUSE update packages are available on many mirror ftp servers all over
the world. While this service is being considered valuable and important
to the free and open source software community, many users wish to be
sure about the origin of the package and its content before installing
the package. There are two verification methods that can be used
independently from each other to prove the authenticity of a downloaded
file or rpm package:
1) md5sums as provided in the (cryptographically signed) announcement.
2) using the internal gpg signatures of the rpm package.
1) execute the command
md5sum <name-of-the-file.rpm>
after you downloaded the file from a SUSE ftp server or its mirrors.
Then, compare the resulting md5sum with the one that is listed in the
announcement. Since the announcement containing the checksums is
cryptographically signed (usually using the key security(a)suse.de)
the checksums show proof of the authenticity of the package.
We disrecommend to subscribe to security lists which cause the
email message containing the announcement to be modified so that
the signature does not match after transport through the mailing
list software.
Downsides: You must be able to verify the authenticity of the
announcement in the first place. If RPM packages are being rebuilt
and a new version of a package is published on the ftp server, all
md5 sums for the files are useless.
2) rpm package signatures provide an easy way to verify the authenticity
of an rpm package. Use the command
rpm -v --checksig <file.rpm>
to verify the signature of the package, where <file.rpm> is the
filename of the rpm package that you have downloaded. Of course,
package authenticity verification can only target an un-installed rpm
package file.
Prerequisites:
a) gpg is installed
b) The package is signed using a certain key. The public part of this
key must be installed by the gpg program in the directory
~/.gnupg/ under the user's home directory who performs the
signature verification (usually root). You can import the key
that is used by SUSE in rpm packages for SUSE Linux by saving
this announcement to a file ("announcement.txt") and
running the command (do "su -" to be root):
gpg --batch; gpg < announcement.txt | gpg --import
SUSE Linux distributions version 7.1 and thereafter install the
key "build(a)suse.de" upon installation or upgrade, provided that
the package gpg is installed. The file containing the public key
is placed at the top-level directory of the first CD (pubring.gpg)
and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de .
- SUSE runs two security mailing lists to which any interested party may
subscribe:
suse-security(a)suse.com
- general/linux/SUSE security discussion.
All SUSE security announcements are sent to this list.
To subscribe, send an email to
<suse-security-subscribe(a)suse.com>.
suse-security-announce(a)suse.com
- SUSE's announce-only mailing list.
Only SUSE's security announcements are sent to this list.
To subscribe, send an email to
<suse-security-announce-subscribe(a)suse.com>.
For general information or the frequently asked questions (faq)
send mail to:
<suse-security-info(a)suse.com> or
<suse-security-faq(a)suse.com> respectively.
