______________________________________________________________________________

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.

   - PHP security problems

     Multiple security bugs were fixed in PHP:

     - Predictable generation of an initialization vector (IV) in the
       mcrypt extension (CVE-2007-2727)

     - Additional cookie attributes could be injected via a session id
       (CVE-2007-3799)

     - Specially crafted files could cause integer overflows in gd and
       leverage them to at least crash gd based applications
       (CVE-2007-3472, CVE-2007-3475, CVE-2007-3476, CVE-2007-3477,
        CVE-2007-3478)

       These GD fixes apply to a copy of the GD library in the PHP sources.

     - Insufficient validation of parameters in the substr_count function
       (CVE-2007-2748).

     - Predictable generating of an initialization vector (IV) in the
       soap extension (CVE-2007-2728)

     PHP4 and PHP5 packages were updated for all SUSE Linux distributions.

   - moodle remote file inclusion

     Moodle was updated to 1.7.2 to fix several problems, including a
     remote file inclusion (CVE-2007-1429).

     Moodle is only on openSUSE 10.2 and was fixed there.

   - Tomcat5 directory traversal

     Tomcat5 was updated to fix a problem, where certain characters of
     the URL were not properly filtered. This allowed directory reverse
     traversal attacks to access the web-root of tomcat. (CVE-2007-0450)

     This affected all our distributions containing tomcat5.

   - lighttpd various security problems

     Multiple bugs in lighttpd allowed remote attackers to crash lighttpd,
     circumvent access restrictions or even execute code.

     These issues are tracked by the Mitre CVE ids:
     CVE-2007-3946, CVE-2007-3947, CVE-2007-3948, CVE-2007-3949,
     CVE-2007-3950

     and have been fixed for SUSE Linux Enterprise 10, SUSE Linux 10.1
     and openSUSE 10.2.

   - Asterisk various security problems

     The Open Source PBS Asterisk was updated to fix multiple bugs
     that allowed remote attackers to crash the asterisk server or even
     execute arbitrary code depending on configuration (CVE-2007-3762,
     CVE-2007-3763, CVE-2007-3764).

     Asterisk was fixed for SUSE Linux 10.0, SUSE Linux 10.1 and
     openSUSE 10.2.

   - libarchive security problems

     Several problems in libarchive were fixed.

     Specially crafted tar-archives could cause programs based on
     libarchive to crash, to run into an endless loop or potentially
     to even execute arbitrary code (CVE-2007-3641, CVE-2007-3644,
     CVE-2007-3645).

   - xpdf buffer overflow

     A buffer overflow in xpdf could be exploited by attackers to
     potentially execute arbitrary code (CVE-2007-3387).

     Various other tools contain copies of the xpdf code and are also
     being updated.  (poppler, libextractor, kdegraphics3-pdf, etc.)

     We have released some of those packages (xpdf, kdegraphics3-pdf)
     already and will release the others soon.

   - evolution format string problem in memo viewer

     Format string problems in the Memo Viewer of evolution could
     be used to potentially execute code when viewing shared memos.
     (CVE-2007-1002)

     Affected are evolution of SLE 10, SUSE Linux 10.1 and openSUSE 10.2.
     For SLE10 the fix was released with Service Pack 1 already, the
     others have received their update now.

   - kvirc command execution

     A bug in the IRC-URI parser allowed attackers to execute arbitrary
     commands by tricking a user into opening a specially crafted URI
     in kvirc (CVE-2007-2951).

     Updated packages have been released for SUSE Linux 10.0 - 10.2.

   - wireshark / ethereal security problems

     Various security problems were fixed in the wireshark 0.99.6 release,
     which were back-ported to wireshark / ethereal:

     CVE-2007-3389: Wireshark allowed remote attackers to cause a
     denial of service (crash) via a crafted chunked encoding in an HTTP
     response, possibly related to a zero-length payload.

     CVE-2007-3390: Wireshark when running on certain systems, allowed
     remote attackers to cause a denial of service (crash) via crafted
     iSeries capture files that trigger a SIGTRAP.

     CVE-2007-3391: Wireshark allowed remote attackers to cause a denial
     of service (memory consumption) via a malformed DCP ETSI packet
     that triggers an infinite loop.

     CVE-2007-3392: Wireshark allowed remote attackers to cause a denial
     of service via malformed (1) SSL or (2) MMS packets that trigger
     an infinite loop.

     CVE-2007-3393: Off-by-one error in the DHCP/BOOTP dissector in
     Wireshark allowed remote attackers to cause a denial of service
     (crash) via crafted DHCP-over-DOCSIS packets.

   - gd various integer overflows

     This update fixes multiple integer overflows in the gd library.
     Specially crafted files could leverage them to at least crash gd
     based applications (CVE-2007-3472, CVE-2007-3475, CVE-2007-3476,
     CVE-2007-3477, CVE-2007-3478).

     GD was updated for all SUSE Linux products, the update was released
     on July 24th.

   - Opera 9.22 release

     Opera was updated to version 9.22 on July 24 to fix numerous defects
     including some security problems. (CVE-2007-3929, CVE-2007-3819,
     CVE-2007-3142)

   - Clamav 0.91.1 release

     This clamav version update to 0.91.1 fixes among other things the
     long startup time of version 0.90.3 as well as a possibility to
     crash clamav with specially crafted rar archives (CVE-2007-3725).

     clamav was updated for all SUSE Linux based products that contain
     clamav.

   - gimp integer overflow in PSD handling

     The image editor GIMP was updated to fix a integer overflow in the
     handling of PSD files. By providing a crafted PSD file and tricking
     the user to open it an attacker could execute code.  (CVE-2007-2949)

     GIMP was updated for all affected SUSE Linux products.
______________________________________________________________________________

2) Pending Vulnerabilities, Solutions, and Work-Arounds

   - Mozilla Firefox 2.0.0.6

     We will likely skip the Firefox 2.0.0.6 update and roll the fixes
     into the 2.0.0.7 release in some weeks, since most problems fixed
     are Windows only.

   - Kernel Update

     We are currently preparing a kernel update for SUSE Linux Enterprise
     10 and SUSE Linux 10.1. A release date is not yet set.
______________________________________________________________________________

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.
