______________________________________________________________________________

1)  problem description, brief discussion, solution, upgrade information

    Tcpdump is a well known tool for administrators to analyze network
    traffic.
      There is a bug in the tcpdump code responsible for handling ISAKMP
    messages. This bug allows remote attackers to destroy a current
    tcpdump session by tricking the tcpdump program with evil ISAKMP
    messages to enter an endless loop.

    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:

    - Opera web browser
    The SuSE Security Team has discovered a flaw in the Opera web browsers
    X.509 certificate handling during the SSL handshake. It allows attackers
    to prompt the Opera web browser with invalid certificates containing
    the public key of the attacker. Thus, he can read or modify the
    HTTPS traffic without notification by the user.
    New packages fixing this problem will be available soon on our ftp
    servers.

    - mc
    By using a special combination of links in archive-files it is possible
    to execute arbitrary commands while mc tries to open it in its VFS.
    The packages will be released soon.

    - mod_gzip (apache-contrib)
    The apache module mod_gzip is vulnerable to remote code execution
    while running in debug-mode. We do not ship this module in debug-mode
    but future versions will include the fix.
    Additionally the mod_gzip code was audited to fix more possible security
    related bugs.
    After more testing a new apache-contrib RPM package will be released.

    - tripwire
    Tripwire is a file integrity checker. The tripwire version on SuSE Linux
    8.2 and 9.0 do crash when a requested file does not exists.
    New packages will be available soon.

    - cvs
    The cvs server-side can be tricked to create files in the root filesystem
    of the server by requesting malformed modules. The permissions on the
    root filesystem normally prevent this malfunction. Additionally the
    package will include a fix for a format-string bug.
    New packages will be available soon.

    - gnome-filesystem
    A script included in the gnome-filesystem package handles temporary
    files insecurely. This script is called by YaST2 with root
    privileges. The bug can be exploited locally to create or overwrite
    arbitrary files in the filesystem. The bug is fixed in our current
    source-tree since November 2003 but nevertheless update packages
    for older SuSE Linux versions will be released soon.

    - XDM (XFree86, xf86)
    A missing check for failure conditions in the PAM code of XDM
    can lead to local root access in conjunction with Kerberos
    and alike. New packages will be released soon.

    - inn
    A buffer overflow in the code for handling control messages
    can be exploited remotely.
    New packages are available on our FTP servers.

    - mpg321
    A format-bug in mpg321 can be exploited (even remotely by HTTP streaming)
    to execute code with the permissions of the user running mpg321 on
    special MP3 files.
    New packages are available on our FTP servers.

    - popper
    Popper handles temporary files in an insecure manner.
    New packages are available on our FTP servers.

    - kdepim3
    It was possible to use a buffer overflow via a special crafted vcard file
    to run code during generating previews. By default it was only possible
    on local filesystems, but the user can enable this also for remote file
    systems.
    New packages are available on our FTP servers.

    - pin
    Pin handles local temporary files in an insecure manner which may lead
    to local privilege escalation.
    Thanks to Stefan Nordhausen <nordhaus at informatik.hu-berlin.de>
    for reporting one of the issues.
    New packages are available on our FTP servers.

    - 3ddiag
    Some 3ddiag scripts handle temporary files in an insecure manner.
    Thanks to Stefan Nordhausen <nordhaus at informatik.hu-berlin.de>
    for reporting some of the issues.
    New packages will be available on our FTP servers soon.

    - mod_auth_shadow (apache-contrib)
    This apache module ignores account expiration dates.
    The update will be released together with mod_gzip.

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 .
