______________________________________________________________________________

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 md5 sums
   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.

   - cacti SQL injection bug

     A SQL injection bug in cacti was fixed.

     The issue is tracked by Mitre CVE ID CVE-2007-6035 and was fixed
     for SUSE Linux 10.0,10.1, and openSUSE 10.2, and 10.3

   - openldap2 remote denial of service

     Multiple flaws were fixed that could cause the OpenLDAP slapd to
     crash (CVE-2007-5707, CVE-2007-5708).

   - phpPgAdmin XSS problems

     Several flaws in phpPgAdmin were fixed that could be exploited
     by remote attackers to perform cross site scripting (XSS) attacks
     (CVE-2007-2865, CVE-2007-5728).

     phpPgAdmin was fixed for openSUSE 10.2.

   - ruby SSL certificate verification process

     ruby was updated to improve the SSL certificate verification
     process. (CVE-2007-5162, CVE-2007-5770) Prior to this update it was
     possible to intercept SSL traffic with a man-in-the-middle attack.

     Fixed ruby packages are available for all distributions with ruby SSL support.

   - perl regular expression buffer overflow

     A buffer overflow in perl's regex engine was fixed.

     The issue is tracked by the Mitre CVE ID CVE-2007-5116 and fixed
     perl packages have been released for all distributions.

   - rubygem-activesupport XSS problem

     A cross site scripting (XSS) bug in rubygem-activesupport allowed
     attackers to execute Javascript code in the context of other web
     sites (CVE-2007-3227).

     rubygem-activesupport packages were released for all affected
     distributions.

   - yast2-core modules loaded from current directory

     A security bug in yast2-core was fixed that allowed local attackers
     to provide malicious yast2 modules to yast2 that are executed with
     root privileges.

     To trigger this vulnerability root has to execute yast2 in an
     untrusted directory (i.e. /tmp), since modules were searched in
     the current working directory first.

     Thanks to Stefan Nordhausen for reporting this to us.

   - librpcsecgss also affected by GSSAPI problems

     A security problem was fixed in the librpcsecgss library used
     by NFSv4 also found in krb5. A invalid packet could underflow
     and potentially cause memory corruption and code execution.
     (CVE-2007-3999)

     It is unknown if the problematic code path is exploitable for
     this package.

   - liblcms ICC profile parsing problem

     Several security bugs were fixed in liblcms that occurred while
     parsing ICC profiles in JPEG images. (CVE-2007-2741) Remote
     attackers can exploit this bug to execute arbitrary commands or
     cause denial-of-service.

     liblcms was updated for all distributions.

2) Pending Vulnerabilities, Solutions, and Work-Arounds

   - SUSE Linux 10.0 going towards end of support

     Starting this week we no longer open new bugs for SUSE Linux 10.0.

     We currently drain the queue of the security problems known before
     and so draw towards end of support in some weeks.

     We strongly recommend upgrading to a newer openSUSE version.

   - Kernel Updates

     We are currently preparing kernel updates for SUSE Linux 10.1,
     openSUSE 10.3 and SUSE Linux Enterprise 10 to fix various security
     problems and lots of bugs.

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.
