______________________________________________________________________________

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 
       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 
       to verify the signature of the package, where  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  .
