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

    Gaim is a multi-protocol instant-messaging client. Stefan Esser found
    12 vulnerabilities in gaim that can lead to a remote system compromise
    with the privileges of the user running GAIM.
    The GAIM package that SUSE LINUX ships is affected by just two of these
    bug:
        - Yahoo Packet Parser Overflow
        - HTTP Proxy Connect Overflow

    The first vulnerability is easy to exploit and results in a classic stack
    overflow which can be used to execute arbitrary code.
    The latter vulnerability requires the gaim client use a HTTP proxy under
    the control of the attacker. The exploitation of this bug results in
    arbitrary code execution too.

    There is no known workaround.

    Please download the update package for your distribution and verify its
    integrity by the methods listed in section 3) of this announcement.
    Then, to apply the update use the command "rpm -Fhv file.rpm".
    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:

    - kernel binaries for SLES8 AMD64
    Due to a human failure the kernel binaries of SuSE Linux Enterprise
    Server 8 for AMD64 lack the fix described in SuSE-SA:2004:003. The
    kernel-source packages and the packages for IA64 are *not* affected.
    New packages are available at our maintenance-web.

    - 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.
    New packages are available on our FTP servers.

    - 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 possibly security
    related bugs.
    After more testing a new apache-contrib RPM package will be released.

    - tripwire
    Tripwire is a file integrity checker. The version of tripwire included
    with SuSE Linux 9.0 crashs when a requested file does not exists.
    New packages are available on our FTP servers.

    - 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 or
    other authentication methods.
    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 these issues.
    New packages are available on our FTP servers.

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

    - cvsup
    cvsup uses a library path which is world-writeable. This behavior
    can lead to local privilege escalation.
    Thanks to Matthias Andree for notifying us.
    Upcoming SuSE Linux versions have an automatic check enabled to detect
    these types of bugs.
    New packages are available on our FTP servers.

    - nmap
    Due to a bad interaction between kernel and user-space for pre-
    calculated IP checksums nmap did not work on SUSE LINUX 9.0.
    New packages are available on our FTP servers.

    - netpbm
    Some tools in the netpbm suite create files in an insecure manner
    that can lead to local privilege escalation.
    New packages will be available soon.

    - zebra
    Local users can send malicious netlink messages that cause
    denial-of-service conditions in zebra.
    New packages will be available soon.

    - quagga
    Local users can send malicious netlink messages that cause
    denial-of-service conditions in the routing-daemon quagga.
    New packages are available on our FTP servers.

    - tcpdump
    The code for handling ISAKMP and RADIUS messages contained bugs
    which allowed remote attackers to crash tcpdump or to execute
    arbitrary code.
    New packages are available on our FTP servers.

    - mod_python
    A remote denial-of-service attack can be triggered against the Apache
    web server by sending a specific query string that is processed by
    mod_python.
    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 [email protected]), 
       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 "[email protected]" 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 .
