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.

     closes the connection (CVE-2008-5006).
     Affected products: openSUSE 10.3-11.1

   - rsyslog
     rsyslog ignored the $AllowedSender configuration directive,
     therefore accepting log messages from anyone (CVE-2008-5617).
     Additionally imudp logged a message when unauthorized senders tried
     to send to it, therefore allowing attackers to flood the log
     CVE-2008-5618).

   - courier-authlib
     Insufficient quoting allowed attackers to inject SQL statements when
     using the pgsql backend (CVE-2008-2380).
     Affected products: openSUSE 10.3-11.1

   - nfs-utils
     This update of nfs-utils fixes the handling of the tcp wrapper ACLs.

     SLE 10 DEBUGINFO SP2, SLED 10 SP1, SLED 10 SP2, SLES 10 SP1, SLES 10 SP2

   - python
     Integer Overflows in the python imageop module and in the expandtabs method
     potentially allowed attackers to execute arbitrary code (CVE-2008-4864,
     CVE-2008-5031)
     Affected products: openSUSE 10.3-11.0, Novell Linux Desktop 9, Novell Linux
     POS 9, Open Enterprise Server, SLES 9, SLE SDK 10 SP2, SLED 10 SP2,
     SLES 10 SP2

   - jhead
     An update of jhead fixes several security problems:
     - CVE-2008-4575: buffer overflow in DoCommand()
     - CVE-2008-4639: local symlink attack
     - CVE-2008-4640: DoCommand() allowed deletion of arbitrary files
     - CVE-2008-4641: execution of arbitrary shell commands in DoCommand()
     Affected products: openSUSE 10.3-11.1

   - git
     Insufficient quoting of shell characters allowed remote attackers to
     execute arbitrary commands via the git web interface (CVE-2008-5517)
     Affected products: openSUSE 10.3

   - samba
     This update of samba fixes a bug that allowed the client to retrieve
     arbitrary memory content from the server process.  (CVE-2008-4314)
     Additionally another bug was fixed that affects environments that
     enabled registry shares by setting "registry shares = yes". In this case
     an authenticated user is accidently allowed to access the root file-
     system "/". (CVE-2009-0022)
     Affected products: openSUSE 10.3-11.1

   - vinagre
     A format string problem in vinagre potentially allowed malicious VNC
     servers to have a vinagre client that connects to the server execute
     arbitrary code. (CVE-2008-5660)
     Affected products: openSUSE 11.0-11.1

   - opera
     Opera 9.63 fixes the following security problems:
     - Manipulating text input contents can allow execution of
       arbitrary code
     - HTML parsing flaw can cause Opera to execute arbitrary code.
     - Long hostnames in file: URLs can cause execution of arbitrary
       code.
     - Script injection in feed preview can reveal contents of unrelated
       news feeds.
     - Built-in XSLT templates can allow cross-site scripting.
     - Fixed an issue that could reveal random data.
     - SVG images embedded using <img> tags can no longer execute Java or

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 <file>

    replacing <file> with the name of the file containing the announcement.
    The output for a valid signature looks like:

      gpg: Signature made <DATE> using RSA key ID 3D25D3D9
      gpg: Good signature from "SuSE Security Team <security@suse.de>"

    where <DATE> 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 <file.rpm>

    to verify the signature of the package, replacing <file.rpm> 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.
            To subscribe, send an e-mail to
                <opensuse-security+subscribe@opensuse.org>.

    opensuse-security-announce@opensuse.org
        -   SUSE's announce-only mailing list.
            Only SUSE's security announcements are sent to this list.
            To subscribe, send an e-mail to
                <opensuse-security-announce+subscribe@opensuse.org>.
