1) problem description, brief discussion

    The QT-library is an environment for GUI-programming and is used in
    various well-known projects, like KDE.

    Chris Evans found a heap overflow in the BMP image format parser
    (CAN-2004-0691) which can probably be abused by remote attackers to
    execute arbitrary code with the privileges of the user using a
    malformed image as input for a vulnerable QT-based application.
    Additionally a NULL dereference in the GIF parser (CAN-2004-0693)
    was found.
    This lead to more research by other people and revealed another NULL
    dereference in the XPM parser (CAN-2004-0692) found by Marcus Meissner,
    SuSE Security-Team.
    The last two bugs can be used to trigger a remote denial-of-service
    attack against QT-based applications.


2) solution/workaround

    A temporary workaround for this issue is not known.


3) special instructions and notes

    After applying the update make sure all QT-based applications are
    restarted. It would be best to re-login if you use KDE.


4) package location and checksums

    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.

5)  Pending vulnerabilities in SUSE Distributions and Workarounds:

    - opera
    The web-browser opera is affected by several security bugs. Due to
    the nature of this package we are not able to provide security updates
    in a timely manner and have to wait for binary packages to be published
    by "Opera Software".

    - acroread
    iDEFENSE reported a buffer overflow and insecure handling of shell
    meta-chars in acroread code.
    We depend on the release of a new binary package by Adobe.
    An update will be available as soon as possible.

______________________________________________________________________________

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 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  .


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