1) Solved Security Vulnerabilities

   To avoid flooding mailing lists with SUSE Security Announcements for minor
   issues, SUSE Security releases weekly summary reports for the low profile
   vulnerability fixes. The SUSE Security Summary Reports do not list or
   download URLs like the SUSE Security Announcements that are released for
   more severe vulnerabilities.

   Fixed packages for the following incidents are already available on our FTP
   server and via the YaST Online Update.

   - imlib2
     A security problem was fixed in imlib2 where loading a specific XPM
     file could corrupt memory. (CVE-2008-5187)
     Affected products: SLED 10 SP2, SLE SDK 10 (updates for other products
                        were already released)

   - valgrind
     valgrind reads a file .valgrindrc in the current directory.
     Therefore local users could place such a file a world writable
     directory such as /tmp and influence other users' valgrind when it's
     executed there (CVE-2008-4865).
     Affected products: SLES9/SDK (updates for other products were already
                        released)

   - kvm
     Rogue VNC clients could make the built in VNC server of kvm run into
     an infinite loop (CVE-2008-2382)
     An off-by-one bug limited the length of VNC passwords to seven
     instead of eight (CVE-2008-5714)
     Virtualized guests could potentially execute code on the host by
     triggering a buffer overflow in the network emulation code via large
     ethernet frames (CVE-2007-5729)
     Virtualized guests could potentially execute code on the host by
     triggering a heap based buffer overflow in the Cirrus Graphics card
     emulation (CVE-2007-1320).
     Affected products: openSUSE 11.0, 11.1

   - cups
     Previous updates for the PNG and HPGL filters were incomplete and
     are corrected now (CVE-2008-3641, CVE-2008-5286).
     Affected products: openSUSE 10.3, 11.0, SLE10-SP2, SLES9 

   - lynx
     This update of lynx fixes two security bugs:
     - untrusted search path allows execution of arbitrary commands via
       .mailcap or mime.types file (CVE-2006-7234)
     - when advanced mode is enabled and lynx is used as URL handler, remote
       attackers can execute arbitrary commands (CVE-2008-4690)
     Affected products: NLD 9 SDK, SLE SDK 10 SP2, SLES SDK 9 (updates for
                        other products were already released)

   - xterm
     XTerm evaluated various ANSI Escape sequences so that command execution
     was possible if an attacker could pipe raw data to an xterm.
     (CVE-2008-2383)
     (It is usually not recommended to display raw data on an xterm.)
     Affected products: openSUSE 10.3-11.0, SLE10-SP2, (SLES9 packages will
                        be released within this week)

3) 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 containing 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 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 included at the end of this
    announcement.

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

    opensuse-security@opensuse.org
        -   General Linux and SUSE security discussion.
            All SUSE security announcements are sent to this list.
