    ______________________________________________________________________________

    1) problem description, brief discussion

        The Concurrent Versions System (CVS) offers tools which allow developers
        to share and maintain large software projects.
          The current maintainer of CVS reported various problems within CVS
        such as a buffer overflow and memory access problems which have
        been fixed within the available updates.
          The CVE project has assigned the CAN number CAN-2005-0753.

    2) solution/workaround

        There is no easy workaround except shutting down the CVS server.

    3) special instructions and notes

        No special actions need to be taken after installing this update.

    4) package location and checksums

        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 for installation from the maintenance web.

    5) Pending vulnerabilities in SUSE Distributions and Workarounds:

       - IDN (Internationalized Domain Name) cloaking / homograph attacks

         Problems with the IDN / punycode handling that allows non-ASCII
         domain names were reported for every browser.
         
              - The KDE approach is currently filtering on the top level domain.
              - The Mozilla approach is currently to display punycode.
         
         We have released Mozilla Firefox and KDE / konqueror updates for
         this problem, the others (mozilla suite and opera) are still pending.

       - PostgreSQL problems

         Additional PostgreSQL problems were reported:
         - A local user could bypass the EXECUTE permission check for
           functions by using the CREATE AGGREGATE command. CAN-2005-0244
         
         - Other earlier listed problems are already fixed.
         
         We are still working on updates for this problem.

       - new Mozilla security problems

         Several new Mozilla browser security problems have been reported.

         We are currently addressing these issues.

       - OpenOffice_org heap overflow
         A heap overflow was found in the MS Word document handing of
         OpenOffice_org, allowing a remote attacker to execute code via a
         handcrafted .doc file.

         We are preparing updates for this issue.

    ______________________________________________________________________________

    6) 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@suse.de),
           the checksums show proof of the authenticity of the package.
           We recommend against subscribing to security lists that cause the
           e-mail 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
           file name of the rpm package that you have downloaded. Of course,
           package authenticity verification can only target an uninstalled 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 .

      - SUSE runs two security mailing lists to which any interested party may
        subscribe:

        suse-security@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@suse.com>.

        suse-security-announce@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@suse.com>.

        For general information or the frequently asked questions (faq)
