1. Impact

   Multiple security vulnerabilities in certain versions of Mozilla
   (listed below), may result in one or more of the following issues:

   1. A buffer overflow exists that may allow a remote unprivileged user
   the ability to execute arbitrary code with the privileges of a local
   user when that local user has loaded an X Bitmap (XBM) format image
   file or an ICO (Icon Image) image file supplied by an untrusted user
   or website. [Sun CR 6281360]

   This issue is described in the following documents:
     * http://www.niscc.gov.uk/niscc/docs/al-20050614-00488.html?lang=
       en
     * https://bugzilla.mozilla.org/show_bug.cgi?id=295457
     * https://bugzilla.mozilla.org/show_bug.cgi?id=245631

   2. A security vulnerability may allow a malicious website to crash the
   Mozilla browser when the user drags an image across multiple windows.
   [Sun CR 6282190]

   This issue is described in the following document:
     * https://bugzilla.mozilla.org/show_bug.cgi?id=288006

   3. A security vulnerability may allow a malicious website to inject
   content into a frame. This is known as the "frame injection
   vulnerability". [Sun CR 6282170]

   This issue is described in the following documents:
     * https://bugzilla.mozilla.org/show_bug.cgi?id=296850
     * http://www.mozilla.org/security/announce/mfsa2005-51.html

   4. A security vulnerability may allow a malicious website to hang the
   Mozilla web browser creating a Denial of Service (DoS) by providing a
   table with large rowspans or colspans. [Sun CR 6284465]

   This issue is described in the following document:
     * https://bugzilla.mozilla.org/show_bug.cgi?id=141818

2. Contributing Factors

   These issues can occur in the following releases:

   SPARC Platform
     * Mozilla 1.4 downloaded from the Sun Download Center (SDC) (for
       Solaris 8 and Solaris 9)
     * Solaris 10 without patch 119115-10

   x86 Platform
     * Mozilla 1.4 downloaded from the Sun Download Center (SDC) (for
       Solaris 8 and Solaris 9)
     * Solaris 10 without patch 119116-10

   Linux
     * Sun Java Desktop System (JDS) Release 2 without patch 118492-04

   Note: Solaris 7 is not affected by these issues.

   The described issues only occur with the following Mozilla versions:
     * Mozilla 1.4 downloaded from the Sun Download Center (SDC)
     * Mozilla 1.7 bundled with Solaris 10

   Note: Mozilla 1.4 downloaded from the Sun Download Center (SDC) is
   affected by issues numbered 1, 2, and 4 (Sun CRs 6281360, 6282190,
   and 6284465) above.

   To determine the version of Mozilla installed on a system, the
   following command can be used:
    % /usr/sfw/bin/mozilla -version
    Mozilla 1.7, (Sun Java Desktop System), build 2005082415

   To determine the release of JDS for Linux installed on a system, the
   following command can be used:
    % cat /etc/sun-release
    Sun Java Desktop System, Release 2 -build 10b (GA)
    Assembled 30 March 2004

   To determine the version of Mozilla for Linux, run the following
   command on JDS:
    % rpm -qf /usr/bin/mozilla
    mozilla-1.4.1-226


3. Symptoms

   There are no predictable symptoms that would indicate the described
   arbitrary code execution issue (item #1 above) or the frame injection
   vulnerability (item #3 above) have been exploited. 

4. Relief/Workaround

   To reduce the chances of some of the above issues from occurring, turn
   off "image display" by doing the following:
    1. Select "Preferences" under the browser's "Edit" menu
    2. In the "Preferences" window, select the "Privacy and Security"
       category
    3. Click on "Images"
    4. From the Images window, select "Do not load any images"
    5. Click "ok"

5. Resolution

   These issues are addressed in the following releases:

   SPARC Platform
     * Mozilla 1.7 SDC (for Solaris 8 and Solaris 9)
     * Solaris 10 with patch 119115-10 or later

   x86 Platform
     * Mozilla 1.7 SDC (for Solaris 8 and Solaris 9)
     * Solaris 10 with patch 119116-10 or later
