1) problem description, brief discussion, solution, upgrade information
The K Desktop Environment KDE allows to generate postscript previews which
can be viewed via certain konqueror plug-ins for example. The previews
are generated by invoking the ghostscript program but without supplying the
"-dSAFER" option as an argument. This allows embedded code to be executed.
Additionally to the correction made to the postscript generation process,
various other security related bug fixes and patches from KDE 3.0.5a have
been incorporated. For more information regarding these fixes please visit
the URLs given as cross references.
The complete list of fixed packages is as follows:
kdelibs3
kdelibs3-cups
kdebase3
kdebase3-kdm
kdebase3-konqueror
kdebase3-ksysguardd
kdebase3-extra

Due to the large list of update packages we do not provide MD5 sums in this
advisory. This would blow up the advisory and make it unreadable.
Rather we recommend to either update your system via YaST2 where the
auto updater automatically checks the integrity of the packages or to follow
the guideline from section 3, "Package authenticity verification".
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:
- glibc
New glibc packages will be available soon which fix a RPC XDR integer
overflow. The packages are currently being tested.
- pptpd
A buffer overflow was found in the pptpd server. New packages 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@...e.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@...e.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@...e.com
- general/linux/SuSE security discussion.
All SuSE security announcements are sent to this list.
To subscribe, send an email to
<suse-security-subscribe@...e.com>.

- SuSE's announce-only mailing list.
Only SuSE's security announcements are sent to this list.
To subscribe, send an email to
