______________________________________________________________________________

1) Problem Description and Brief Discussion

   The TLS/SSLv3 protocol as implemented in openssl prior to this update
   was not able to associate already sent data to a renegotiated connection.
   This allowed man-in-the-middle attackers to inject HTTP requests in a
   HTTPS session without being noticed.
   For example Apache's mod_ssl was vulnerable to this kind of attack because
   it uses openssl.
   
   It is believed that this vulnerability is actively exploited in the wild to
   get access to HTTPS protected web-sites.
   
   Please note that renegotiation will be disabled for any application using
   openssl by this update and may cause problems in some cases.
   Additionally this attack is not limited to HTTP.

2) Solution or Work-Around

   There is no work-around known. Please install the update.
   Moblin packages will be released later.

3) Special Instructions and Notes

   Please note that this update disables renegotiation for all applications
   using openssl.
   All applications using openssl need to be restarted. You can find out what
   library an application uses with lsof(8) as root.
   If possible restart your system.

4) Package Location and Checksums

   The preferred method for installing security updates is to use the YaST
   Online Update (YOU) tool. YOU detects which updates are required and
   automatically performs the necessary steps to verify and install them.
   Alternatively, download the update packages for your distribution manually
   and verify their integrity by the methods listed in Section 6 of this
   announcement. Then install the packages using the command

     rpm -Fhv 

   to apply the update, replacing  with the filename of the
   downloaded RPM package.

6) Authenticity Verification and Additional Information

  - Announcement authenticity verification:

    SUSE security announcements are published via mailing lists and on Web
    sites. The authenticity and integrity of a SUSE security announcement is
    guaranteed by a cryptographic signature in each announcement. All SUSE
    security announcements are published with a valid signature.

    To verify the signature of the announcement, save it as text into a file
    and run the command

      gpg --verify 

    replacing  with the name of the file where you saved the
    announcement. The output for a valid signature looks like:

      gpg: Signature made  using RSA key ID 3D25D3D9
      gpg: Good signature from "SuSE Security Team "

    where  is replaced by the date the document was signed.

    If the security team's key is not contained in your key ring, you can
    import it from the first installation CD. To import the key, use the
    command

      gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc

  - Package authenticity verification:

    SUSE update packages are available on many mirror FTP servers all over the
    world. While this service is considered valuable and important to the free
    and open source software community, the authenticity and the integrity of
    a package needs to be verified to ensure that it has not been tampered
    with.

    The internal 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, replacing  with the
    filename of the RPM package downloaded. The package is unmodified if it
    contains a valid signature from build@suse.de with the key ID 9C800ACA.

    This key is automatically imported into the RPM database (on
    RPMv4-based distributions) and the gpg key ring of 'root' during
    installation. You can also find it on the first installation CD and at
    the end of this announcement.
