______________________________________________________________________________

1) Problem Description and Brief Discussion

   Various Mozilla family browsers have been updated to their current
   security release versions.

   The Mozilla Seamonkey suite was brought to security update version
   1.0.9.

   The Mozilla Firefox browser was brought to security update version
   1.5.0.12 on Novell Linux Desktop 9 and 2.0.0.4 on SUSE Linux Enterprise
   10, SUSE Linux 10.0, 10.1 and openSUSE 10.2.

   The Mozilla Thunderbird mailreader was brought to security update
   version 1.5.0.12 on SUSE Linux 10.0, 10.1 and openSUSE 10.2.

   Note that most of the packages were released some weeks ago already,
   only MozillaFirefox for SLE10 Service Pack 1 was missing and released
   today.

   The following security issues have been fixed:
   - MFSA 2007-17 / CVE-2007-2871:

     Chris Thomas demonstrated that XUL popups opened by web content
     could be placed outside the boundaries of the content area. This
     could be used to spoof or hide parts of the browser chrome such as
     the location bar.

   - MFSA 2007-16 / CVE-2007-2870:

     Mozilla contributor moz_bug_r_a4 demonstrated that the
     addEventListener method could be used to inject script into another
     site in violation of the browser's same-origin policy. This could
     be used to access or modify private or valuable information from
     that other site.

   - MFSA 2007-15 / CVE-2007-1558:

     Gaëtan Leurent informed us of a weakness in APOP authentication
     that could allow an attacker to recover the first part of your mail
     password if the attacker could interpose a malicious mail server on
     your network masquerading as your legitimate mail server. With normal
     settings it could take several hours for the attacker to gather
     enough data to recover just a few characters of the password. This
     result was presented at the Fast Software Encryption 2007 conference.

   - MFSA 2007-14 / CVE-2007-1362:

     Nicolas Derouet reported two problems with cookie handling in
     Mozilla clients.  Insufficient length checks could be use to exhaust
     browser memory and so to crash the browser or at least slow it done
     by a large degree.

     The second issue was that the cookie path and name values were not
     checked for the presence of the delimiter used for internal cookie
     storage, and if present this confused future interpretation of the
     cookie data. This is not considered to be exploitable.

   - MFSA 2007-13 / CVE-2007-2869:

     Marcel reported that a malicious web page could perform a denial
     of service attack against the form autocomplete feature that would
     persist from session to session until the malicious form data
     was deleted. Filling a text field with millions of characters and
     submitting the form will cause the victim's browser to hang for up
     to several minutes while the form data is read, and this will happen
     the first time autocomplete is triggered after every browser restart.

     No harm is done to the user's computer, but the frustration caused
     by the hang could prevent use of Thunderbird if users don't know
     how to clear the bad state.

   - MFSA 2007-12 / CVE-2007-2867 / CVE-2007-2868

     As part of the Thunderbird 2.0.0.4 and 1.5.0.12 update releases
     Mozilla developers fixed many bugs to improve the stability of
     the product. Some of these crashes that showed evidence of memory
     corruption under certain circumstances and we presume that with
     enough effort at least some of these could be exploited to run
     arbitrary code.

     Without further investigation we cannot rule out the possibility
     that for some of these an attacker might be able to prepare memory
     for exploitation through some means other than JavaScript, such as
     large images.

   - MFSA 2007-11 / CVE-2007-1562:

     Incorrect FTP PASV handling could be used by malicious ftp servers     to do a rudimentary port scanning of for instance internal networks
     of the computer the browser is running on.

2) Solution or Work-Around

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

3) Special Instructions and Notes

   Please restart running instances of the Mozilla browsers.

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.
            All SUSE security announcements are sent to this list.
            To subscribe, send an e-mail to
                .

    opensuse-security-announce@opensuse.org
        -   SUSE's announce-only mailing list.
            Only SUSE's security announcements are sent to this list.
            To subscribe, send an e-mail to
