______________________________________________________________________________

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.

   - dovecot character set injection
     Dovecot might have been affected by the multibyte character set
     SQL injection issues for instance described in CVE-2006-2314.

     This patch fixes the MySQL and PostgreSQL backend to use the correct
     quoting methods when passing user supplied strings.

     All SUSE Linux versions containing dovecot were affected by this
     problem.

   - openldap2 self write access problems
     A security problem was fixed in openldap concerning Access Control
     Processing that allowed users with "selfwrite" access to an
     attribute to modify arbitrary values of that attribute, instead of
     just allowing them to add/delete their own DN to/from that attribute.

     All SUSE Linux based products are affected by this problem.

   - gtetrinet remote buffer overflow
     Malicious tetrinet servers could overflow a buffer within the
     gtetrinet client, making it possible to execute code.

     This is tracked by the Mitre CVE ID CVE-2006-3125 and affects all
     SUSE Linux versions.

   - ruby "safe level" bypass
     A security fix for ruby was released. An attacker could bypass the
     "safe level" checks.

     This is tracked by the Mitre CVE ID CVE-2006-3694 and affects all
     SUSE Linux based products.

   - sendmail denial of service
     A denial of service problem in sendmails header processing could
     be used to crash sendmail due to referencing a freed variable.

     This is tracked by the Mitre CVE ID CVE-2006-4434 and affects all
     SUSE Linux based products.

   - rubygem-actionpack remote code injection
     A remote code injection bug was fixed in rubygem-actionpack.
     The routing code allowed injection using specially crafted headers.

     This problem was assigned the Mitre CVE IDs CVE-2006-4111 and
     CVE-2006-4112 and affected only the SLE 10 SDK.

   - streamripper remote buffer overflow
     This update fixes a buffer overflow in the HTTP header parsing
     in streamripper.

     This bug can be exploited to cause a denial-of-service attack and
     possibly execute arbitrary code via crafted HTTP headers sent by
     malicious servers.

     This is tracked by the Mitre CVE ID CVE-2006-3124 and affects SUSE
     Linux 9.2 and 9.3.

   - alsaplayer remote buffer overflow
     Various bugs were fixed in alsaplayer that could lead to a denial of
     service or even buffer overflows caused by malicious remote servers.

     This problem is tracked by the Mitre CVE ID CVE-2006-4089 and
     affects SUSE Linux 9.2 and 9.3.
______________________________________________________________________________

2) Pending Vulnerabilities, Solutions, and Work-Arounds

   - kernel security problems

     We are currently QA testing kernel updates for all 2.6 based
     SUSE Linux based products to fix various security issues.

     Security issues to be fixed by this round of updates:
     - CVE-2006-3745: A double user space copy in a SCTP ioctl allows
                 local attackers to overflow a buffer in the kernel,
                 potentially allowing code execution and privilege
                 escalation.

     - CVE-2006-4093: Local attackers were able to crash PowerPC systems
                 with PPC970 processor using a not correctly disabled
                 privileged instruction ("attn").

     - CVE-2006-3468: Remote attackers able to access an NFS of a ext2 or
                 ext3 filesystem can cause a denial of service (file
                 system panic) via a crafted UDP packet with a V2
                 lookup procedure that specifies a bad file handle
                 (inode number), which triggers an error and causes an
                 exported directory to be remounted read-only. [#192988]

   - php4/php5 security problems

     We are also preparing new PHP4 and PHP5 update packages to fix
     the currently known PHP security problems. This affects all
     distributions.
______________________________________________________________________________

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:

    suse-security@suse.com
        -   General Linux and SUSE security discussion.
            All SUSE security announcements are sent to this list.
            To subscribe, send an e-mail to
