______________________________________________________________________________

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.

   - netpbm various buffer overflows

     This update fixes a buffer overflow in the RGBA-palette code. This
     bug can be abused to trigger a denial-or-service attack by feeding
     untrusted data to "pnmtopng -alpha" (maybe via a remote service like
     a CGI, MUA, etc.). The execution of arbitrary code is theoretically
     possible but very unlikely.  Another possible buffer overflow that
     can occur while handling a text line was fixed too.

     This is tracked by the Mitre CVE ID CVE-2005-3632 and CVE-2005-3662.

     All SUSE Linux based products are affected.

   - opera remote execution

     The Opera web browser was updated to version 8.51, fixing the
     following security problem:

     Insufficient quoting of shell meta characters in the opera start
     script allowed to execute arbitrary commands if URLs with such
     characters were passed to the script (CVE-2005-3750).

     We released this update two times for SUSE Linux 9.x, the first
     time the update was broken due to libstdc++ dependency problems,
     the second update, released Thursday, fixes this breakage.

     SUSE Linux 9.0 up to 10.0 are affected.

   - inkscape svg importer buffer overflow

     A buffer overflow in the SVG importer of inkscape could potentially
     be exploited to execute arbitrary code when opening a crafted
     SVG file.

     This is tracked by the Mitre CVE  ID CVE-2005-3737.

     SUSE Linux 9.2 up to 10.0 are affected by this problem.

   - apache2-worker memory leak
     A memory leak in apache2-worker that allowed remote attackers to
     exhaust all available memory was fixed.

     This is tracked by the Mitre CVE ID CVE-2005-2970.

     All SUSE Linux based products containing apache2-worker were
     affected.

   - mozilla-mail enigmail encryption problem

     Upon sending an encrypted mail the Mozilla Mail plugin enigmail
     could accidentally encrypt it for the wrong recipient.  During QA
     of the update it was found that in various older distributions the
     plugin is not functional at all (and so not affected).

     This issue is tracked by the Mitre CVE ID CVE-2005-3256.

     The problem affects all SUSE Linux based products containing Mozilla.

   - sylpheed-claws buffer overflow in import plugins

     Buffer overflows in various address book import filters of
     Sylpheed/Sylpheed-Claws was fixed.

     This is tracked by the Mitre CVE ID CVE-2005-3354.

     SUSE Linux 9.0 up to 10.0 were affected by this problem.

   - phpMyAdmin various problems

     phpMyAdmin was updated to fix several security problems:

     - Multiple cross-site scripting (XSS) bugs (CVE-2005-3301,
       CVE-2005-2869, PMASA-2005-5).

     - Multiple file inclusion vulnerabilities that allowed an attacker
       to include arbitrary files (CVE-2005-3300, CVE-2005-3301,
       PMASA-2005-5).

     - A bug that could lead to 'HTTP response splitting'
       (CVE-2005-3621, PMASA-2005-6).

     Exploits for this have been seen in the wild.

     SUSE Linux 9.0 up to 10.0 are affected.

   - gnump3d various problems

     The MP3 streaming server gnump3d was updated to fixes the following
     security problems:

     - Several cross-site-scripting bugs (CVE-2005-3424, CVE-2005-3425)
     - Insecure use of files in /tmp (CVE-2005-3349)
     - Several directory-traversal bugs (CVE-2005-3123, CVE-2005-3355)

   - Squid crashes

     This update of Squid in SUSE Linux 9.0 fixes some bugs that lead
     to crashes.  This bugs were introduced by a previous security-update
     (SUSE-SA:2005:053).

     Please note that this is a version upgrade so you should do the
     following steps: - delete the old cache - adapt the configuration
     file to new options - "clientProcessHit: Vary object loop!" message
     can be ignored

     Only SUSE Linux 9.0 is affected.  The issue is tracked by the Mitre
     CVE ID CVE-2005-3322.

   - php4 / php5 security update broken

     We released a security update for PHP 4 and PHP 5 for all SUSE
     Linux based products.

     This update is broken when PHP applications are used together with
     the Apache "mod_rewrite" module.

     We are working on a fix for this problem and will release updated
     fixed packages as soon as possible.
______________________________________________________________________________

2) Pending Vulnerabilities, Solutions, and Work-Arounds

   - Kernel updates
     We are currently preparing kernel security and bugfix updates for all
     our products.

     The first to be released will be a SUSE Linux 10.0 kernel update next week,
     followed by updates for the other distributions.

     The updates will be separately announced.

______________________________________________________________________________

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.
