______________________________________________________________________________

1) problem description, brief discussion

    The mod_ssl apache module, as part of our apache2 package, enables
    the apache webserver to handle the HTTPS protocol.
      Within the mod_ssl module, two Denial of Service conditions in the
    input filter have been found. The CVE project assigned the identifiers    CAN-2004-0748 and CAN-2004-0751 to these issues.

2) solution/workaround

    As temporary workaround you may disable the mod_ssl module in your
    apache configuration and restart the apache process without SSL
    support.

3) special instructions and notes

    As a dependency you also need to update the libapr0 package and
    one of the apache2-prefork or apache2-worker package, depending
    on whether you use the -prefork or -worker configuration.
      After successfully updating the apache2 packages, you need to
    invoke the following command as root:

      rcapache2 restart

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:

    - mysql
    New mysql packages are available on our ftp servers, fixing a tmp
    race condition in the mysqlhotcopy script.

    - mozilla
    We are in the process of releasing updates for mozilla (and related
    browsers), fixing various issues: CAN-2004-0597, CAN-2004-0718,
    CAN-2004-0722, CAN-2004-0757, CAN-2004-0758, CAN-2004-0759, CAN-2004-0760,
    CAN-2004-0761, CAN-2004-0762, CAN-2004-0763, CAN-2004-0764 and
    CAN-2004-0765.
    We will give you concrete details in a separate mozilla advisory when the
    updates are available.

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  .
