     * Category: Security

       Operating System, Solaris 8 Operating System
     * BugIDs: 6447023

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 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 ten separate memory
   corruption issues:
     * http://www.mozilla.org/security/announce/mfsa2006-32.html

   This Sun Alert corresponds to four of the issues described in the
   Mozilla advisory above:

   Memory corruption involving BoxObjects (Neil Rashbrook):
     * https://bugzilla.mozilla.org/show_bug.cgi?id=329219

   Memory corruption involving BoxObjects (Boris Zbarsky):
     * https://bugzilla.mozilla.org/show_bug.cgi?id=326931

   Potential integer overflow in jsstr tagify (Georgi Guninski):
     * https://bugzilla.mozilla.org/show_bug.cgi?id=335535

   Content-implemented tree views can corrupt memory (Boris Zbarsky):
     * https://bugzilla.mozilla.org/show_bug.cgi?id=326501

   Additional references:

   CVE-2006-2779 describes nine of the ten issues documented in Mozilla
   advisory MFSA 2006-32 which includes the above issues 329219, 326931,
   and 326501.
     * http://cve.mitre.org/cgi-bin/cvename.cgi?name=2006-2779

   CVE-2006-2780 describes the tenth issue documented in Mozilla advisory
   MFSA 2006-32, the integer overflow in the jsstr tagify, 335535.
     * http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2780

   CERT VU#466673 references all ten issues described in Mozilla advisory
   MFSA 2006-32.
     * http://www.kb.cert.org/vuls/id/466673

2. Contributing Factors

   This issue 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 119115-28

   x86 Platform
     * Mozilla 1.7 (for Solaris 8 and 9) without patch 120672-06
     * Mozilla 1.7 (for Solaris 10) without patch 119116-28

   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 these
   security fixes.

   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

   The Mozilla browser may exit unexpectedly if these issues were
   exploited to cause a Denial of Service. There are no predictable
   symptoms that would indicate the described issues have been exploited
   to execute arbitrary code. 

4. Relief/Workaround

   To work around the issues described in this Sun Alert, disable
   JavaScript by doing the following:
    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 119115-28 or later
