______________________________________________________________________________

1) Problem Description and Brief Discussion

   The mozilla browsers in old products and Mozilla Seamonkey in SUSE
   Linux 10.1 were brought to Mozilla Seamonkey to version 1.0.8 and
   Mozilla Thunderbird was brought to version 1.5.0.10 to fix various
   security issues.

   Note that Mozilla Firefox for all distributions and Mozilla
   seamonkey for openSUSE 10.2 was already released and announced in
   SUSE-SA:2007:019.

   Please also see
     https://www.mozilla.org/en-US/security/known-vulnerabilities/
   for more details.

   The updates include fixes to the following security problems:
   - MFSA 2007-01: As part of the Firefox 2.0.0.2  and 1.5.0.10 update
     releases several bugs were fixed to improve the stability of the
     browser. Some of these were crashes that showed evidence of memory
     corruption and we presume that with enough effort at least some of
     these could be exploited to run arbitrary code. These fixes affected
     the layout engine (CVE-2007-0775), SVG renderer (CVE-2007-0776)
     and javascript engine (CVE-2007-0777).

   - MFSA 2007-02: Various enhancements were done to make XSS exploits
     against websites less effective. These included fixes for invalid
     trailing characters (CVE-2007-0995), child frame character set
     inheritance (CVE-2007-0996), password form injection (CVE-2006-6077),
     and the Adobe Reader universal XSS problem.

   - MFSA 2007-03/CVE-2007-0778: AAd reported a potential disk cache
     collision that could be exploited by remote attackers to steal
     confidential data or execute code.

   - MFSA 2007-04/CVE-2007-0779: David Eckel reported that browser UI
     elements--such as the host name and security indicators--could be
     spoofed by using a large, mostly transparent, custom cursor and
     adjusting the CSS3 hotspot property so that the visible part of
     the cursor floated outside the browser content area.

   - MFSA 2007-05: Manually opening blocked popups could be exploited by
     remote attackers to allow XSS attacks (CVE-2007-0780) or to execute
     code in local files (CVE-2007-0800).

   - MFSA 2007-06:
     Two buffer overflows were found in the NSS handling of Mozilla.

     CVE-2007-0008: SSL clients such as Firefox and Thunderbird can suffer
     a buffer overflow if a malicious server presents a certificate
     with a public key that is too small to encrypt the entire "Master
     Secret". Exploiting this overflow appears to be unreliable but
     possible if the SSLv2 protocol is enabled.

     CVE-2007-0009: Servers that use NSS for the SSLv2 protocol can
     be exploited by a client that presents a "Client Master Key" with
     invalid length values in any of several fields that are used without
     adequate error checking. This can lead to a buffer overflow that
     presumably could be exploitable.

   - MFSA 2007-06/CVE-2007-0981: Michal Zalewski demonstrated that setting
     location.hostname to a value with embedded null characters can
     confuse the browsers domain checks. Setting the value triggers a
     load, but the networking software reads the hostname only up to
     the null character while other checks for "parent domain" start at
     the right and so can have a completely different idea of what the
     current host is.

   - MFSA 2007-08/CVE-2007-1092: Michal Zalewski reported a memory
     corruption vulnerability in Firefox 2.0.0.1 involving mixing
     the onUnload event handler and self-modifying document.write()
     calls. This flaw was introduced in Firefox 2.0.0.1 and 1.5.0.9 and
     does not affect earlier versions; it is fixed in Firefox 2.0.0.2
     and 1.5.0.10.

   - MFSA 2007-09/CVE-2007-0994: moz_bug_r_a4 reports that the fix for
     MFSA 2006-72 in Firefox 1.5.0.9 and Firefox 2.0.0.1 introduced
     a regression that allows scripts from web content to execute
     arbitrary code by setting the src attribute of an IMG tag to a
     specially crafted javascript: URI.  The same regression also caused
     javascript: URIs in IMG tags to be executed even if JavaScript
     execution was disabled in the global preferences. This facet was
     noted by moz_bug_r_a4 and reported independently by Anbo Motohiko.

2) Solution or Work-Around

   There is no known workaround, please install the update packages.

3) Special Instructions and Notes

   Please close and restart all running instances of Mozilla after the update..

4) Package Location and Checksums

   The preferred method for installing security updates is to use the YaST
   Online Update (YOU) tool. YOU detects which updates are required and
   automatically performs the necessary steps to verify and install them.
   Alternatively, download the update packages for your distribution manually
   and verify their integrity by the methods listed in Section 6 of this
   announcement. Then install the packages using the command

     rpm -Fhv 

   to apply the update, replacing  with the filename of the
   downloaded RPM package.

6) 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 where you saved 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 the integrity of
    a package needs to be verified to ensure that it has not been tampered
    with.

    There are two verification methods that can be used independently from
    each other to prove the authenticity of a downloaded file or RPM package:

    1) Using the internal gpg signatures of the rpm package
    2) MD5 checksums as provided in this announcement

    1) 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 at
       the end of this announcement.

    2) If you need an alternative means of verification, use the md5sum
       command to verify the authenticity of the packages. Execute the command

         md5sum 

       after you downloaded the file from a SUSE FTP server or its mirrors.
       Then compare the resulting md5sum with the one that is listed in the
       SUSE security announcement. Because the announcement containing the
       checksums is cryptographically signed (by security@suse.de), the
       checksums show proof of the authenticity of the package if the
       signature of the announcement is valid. Note that the md5 sums
       published in the SUSE Security Announcements are valid for the
       respective packages only. Newer versions of these packages cannot be
       verified.

  - SUSE runs two security mailing lists to which any interested party may
    subscribe:

    opensuse-security@opensuse.org
        -   General Linux and SUSE security discussion.
