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.

   - java-1_6_0-ibm
     IBM Java 6 SR9 FP1 was updated to fix a critical security bug in float
     number handling.
     CVE-2010-4476: The Java Runtime Environment hangs forever when converting
     "2.2250738585072012e-308" to a binary floating-point number.
     Affected Products: SLE10-SP4

   - java-1_5_0-ibm
     IBM Java 5 was updated to SR 12 FP 4 fixing various security issues.
     For more details, please check the IBM JDK Alerts page:
           http://www.ibm.com/developerworks/java/jdk/alerts/
     Following CVE entries are referenced by this update:
     CVE-2010-4447, CVE-2010-4448, CVE-2010-4450, CVE-2010-4454, CVE-2010-4462,
     CVE-2010-4465, CVE-2010-4466, CVE-2010-4468, CVE-2010-4471, CVE-2010-4473,
     CVE-2010-4475
     Affected Products: SLES9, SLE10-SP3, SLE10-SP4

   - java-1_4_2-ibm
     IBM Java 1.4.2 SR13 was updated to FP8 to fix various bugs and security
     issues.
     Following security issues were fixed:
     - CVE-2010-1321: The kg_accept_krb5 function in krb5/accept_sec_context.c
       in the GSS-API library in MIT Kerberos 5 (aka krb5) through 1.7.1 and 1.8
       before 1.8.2, as used in kadmind and other applications, does not properly
       check for invalid GSS-API tokens, which allows remote authenticated users to
       cause a denial of service (NULL pointer dereference and daemon crash) via an
       AP-REQ message in which the authenticator's checksum field is missing.
     - CVE-2010-3574: Unspecified vulnerability in the Networking component in
       Oracle Java SE and Java for Business 6 Update 21, 5.0 Update 25, 1.4.2_27,
       and 1.3.1_28 allows remote attackers to affect confidentiality, integrity,
       and availability via unknown vectors. NOTE: the previous information was
       obtained from the October 2010 CPU. Oracle has not commented on claims from
       a reliable downstream vendor that HttpURLConnection does not properly check
       for the allowHttpTrace permission, which allows untrusted code to perform
       HTTP TRACE requests. 
     - CVE-2010-4476: The Java Runtime Environment hangs forever when converting
       "2.2250738585072012e-308" to a binary floating-point number.
     Affected Products: SLE10-SP4

   - postfix
     postfix did not clear the receive buffer after the STARTTLS command.
     A man-in-the middle could therefore inject commands in the unencrypted
     stream that get interpreted in the encrypted phase after STARTTLS
     (CVE-2011-0411).
     Affected Products: SLE10-SP3, SLE10-SP4, SLE11-SP1, openSUSE 11.2, 11.3, 11.4

   - dhcp6
     A rogue dhcp server could instruct clients to use a host name that
     contains shell meta characters. Since many scripts in the system do
     not expect unusal characters in the system's host name the dhcp
     client needs to sanitize the host name offered by the server
     (CVE-2011-0997).
     Affected Products: SLES9, SLE10-SP2, SLE10-SP3, SLE10-SP4, SLE11-SP1, openSUSE 11.2, 11.3, 11.4

   - dhcpcd
     This update fixes the following security issue:
       A rogue DHCP server could instruct clients to use a host name that
     contains shell meta characters. Since many scripts in the system do
     not expect unusal characters in the system's host name the DHCP
     client needs to sanitize the host name offered by the server
     (CVE-2011-0996).
       Note this update is actually just a re-release of the previous one.
     The security fix made dhcpcd crash if the DHCP server sent a SIP
     option that was not decodable. This update also allows spaces in the
     domain name option again as some DHCP servers abuse the option as
     DNS search list.
     This update also fixes the following non-security issues:
       - 564441: e1000 and dhcpd hickup
       - 579438: endless loop after adding wlan usb stick (with dhcp ip lease
                 time infinity)
       - 654649: dhcpcd ignores -G (--nogateway) option and sets default route
       - 657402: dhcpcd sends RENEWAL as ethernet broadcast instead of unicast
       - 668194: dhcp client not working properly in Xen domU due to partial
                 checksum offload
       - 672038: dhcpcd sends RENEWAL as ethernet broadcast instead of unicast

   - mono-addon-bytefx-data-mysql/bytefx-data-mysql
     Mono had loaded shared libraries from the current directory (CVE-2010-4159)
     and was also vunerable to a padding oracle attack (CVE-2010-3332)
     Affected Products: SLE10-SP3, SLE10-SP4, SLE11, SLE11-SP1

   - dbus-1
     Local users could crash the D-Bus daemon by sending a specially crafted
     message (CVE-2010-4352). This update also properly fixes CVE-2008-3834
     and CVE-2009-1189.
     Affected Products: SLE10-SP3, SLE10-SP4, SLE11-SP1, openSUSE 11.2, 11.3

   - libtiff/libtiff-devel
     Specially crafted tiff files could cause a heap-based buffer overflow
     in the thunder-decoder (CVE-2011-1167).
     Directories with a large number of files could cause an integer
     overflow in the tiffdump tool (CVE-2010-4665)
     Affected Products: SLES9, SLE10-SP3, SLE11-SP1, openSUSE 11.2, 11.3, 11.4

   - cifs-mount/libnetapi-devel
     With this update samba is not prone to a remote denial of service
     attack anymore. (CVE-2011-0719)
     Additionally this update also fixes the following reliability bugs:
     - leaving childs in "zombie" state
     - adding new printers without restart
     - GSSAPI lock AD user account
     - printer drivers from Windows 64-bit failing
     - MIGRATE PRINTERS failing on 64-bit
     Affected Products: SLE10-SP3, SLE10-SP4, SLE11-SP1, openSUSE 11.2, 11.3

   - rubygem-sqlite3
     The package contained some world-writable files. Local users could
     exploit that to inject arbitrary code into programs using rubygem-sqlite3
     (CVE-2011-0995).
     Affected Products: SLE11-SP1

   - gnutls
     The SSL-renegotiation "authentication gap" has been fixed in GnuTLS. 
     (CVE-2009-3555)
     Also an integer size issue was fixed which lead to incorrectly accepted
     certificates.
     Affected Products: SLES9

   - libpolkit0
     A race condition exists in pkexec while trying to
     determine its caller which could lead to privilege escalation.
     CVE-2011-1485 has been assigned to this issue.
     Affected Products: openSUSE 11.3, 11.4

   - udisks
     This update of udisks improves input validation. Before it was possible
     to load arbitrary LKMs. (CVE-2010-4661: CVSS v2 Base Score: 4.6)
     Affected Products: openSUSE 11.3, 11.4

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
