1. Impact

   A number of memory corruption vulnerabilities have been found in the
   Mozilla application which may allow a remote user who is able to
   create a web page which is visited by a local user using the Mozilla
   browser, or who sends a specially crafted email that is read by a
   local user using Mozilla, to either cause the Mozilla application to
   crash or execute arbitrary code via Javascript with the privileges of
   the user running Mozilla. The ability of a remote user to cause the
   Mozilla application to crash is a type of Denial of Service (DoS).

   The following Mozilla advisory describes nine separate memory
   corruption issues:
     * http://www.mozilla.org/security/announce/mfsa2006-55.html

   This Sun Alert corresponds to the following five issues described in
   the Mozilla advisory above:

   FireMenuItemActiveEvent called at unsafe times (Boris Zbarsky):
     * https://bugzilla.mozilla.org/show_bug.cgi?id=336162

   Potential string class buffer overruns in out-of-memory case (Darin
   Fisher, Daniel Veditz):
     * https://bugzilla.mozilla.org/show_bug.cgi?id=284219

   Crashes involving table row and column groups (Jesse Ruderman, Martijn
   Wargers):
     * https://bugzilla.mozilla.org/show_bug.cgi?id=331679
     * https://bugzilla.mozilla.org/show_bug.cgi?id=329900

   crypto.generateCRMFRequest callback can run on deleted context
   (shutdown):
     * https://bugzilla.mozilla.org/show_bug.cgi?id=337462

   Note: Mozilla 1.7 is not affected by the below vulnerabilities
   mentioned in the advisory:

   Crashes referencing removed nodes (Jesse Ruderman, Martijn Wargers):
     * https://bugzilla.mozilla.org/show_bug.cgi?id=338391
     * https://bugzilla.mozilla.org/show_bug.cgi?id=340733

     * http://www.us-cert.gov/cas/techalerts/TA06-208A.html

2. Contributing Factors

   These issues can occur in the following releases:

   SPARC Platform
     * Mozilla 1.7 (for Solaris 8 and 9) without patch 120671-06
     * Mozilla 1.7 (for Solaris 10) without patch 119115-30

   x86 Platform
     * Mozilla 1.7 (for Solaris 8 and 9) without patch 120672-06
     * Mozilla 1.7 (for Solaris 10) without patch 119116-30

   Note: Mozilla 1.4 may be vulnerable to one or more of these security
   issues. Customers are advised to upgrade to Mozilla 1.7 to get the
   security fixes once they are available.

   To determine the version of Mozilla on a Solaris system, the following
   command can be run:
    % /usr/sfw/bin/mozilla -version
    Mozilla 1.7, (Sun Java Desktop System), build 2005031721


3. Symptoms

   There are no predictable symptoms that would indicate the described
   issues have been exploited. 

4. Relief/Workaround

   Some of the memory corruption vulnerabilities may be mitigated by
   disabling Javascript:
    1. Open the "Preferences" dialog from the Edit menu
    2. Select the "Advanced" tree
    3. Select the "Scripts & Plug-ins" leaf
    4. Uncheck the "Navigator and Mail & Newsgroups" check boxes
    5. Click the "OK" button

5. Resolution

   This issue is addressed in the following releases:

   SPARC Platform
     * Mozilla 1.7 (for Solaris 8 and 9) with patch 120671-06 or
       later
     * Mozilla 1.7 (for Solaris 10) with patch 119115-30 or later
