______________________________________________________________________________

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 
       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@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 
       to verify the signature of the package, where  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@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 .
