   1. Impact Multiple security vulnerabilities in Mozilla may result in
   one or more of the following issues:

   1. A buffer overflow exists that may allow a a remote unprivileged
   user the ability to execute arbitrary code with the privileges of a
   local user when that local user has loaded a Portable Network Graphics
   (PNG) format image file supplied by an untrusted remote user.

   This issue is described in the following document:

     * [2]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0687

   2. An integer overflow and a heap corruption exists in JavaScript that
   may allow an unprivileged user the ability to execute arbitrary code
   with the privileges of a local user running Mozilla.

   This issue is described in the following document:

     * [3]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0722
       
   3. A heap overflow exists that could allow a malicious POP3 server to
   send a carefully crafted response that may allow a remote unprivileged
   user the ability to execute arbitrary code with the privileges of a
   local user running Mozilla.

   This issue is described in the following document:

     * [4]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0757

   4. Additional heap overflows and double frees exist that could allow a
   malicious POP3 server to send a carefully crafted response that may
   cause a Denial of Service (DOS) attack for the client or may allow a
   remote unprivileged user the ability to execute arbitrary code with
   the privileges of the local user running Mozilla.

   This issue is described in the following document:

     * [5]https://bugzilla.mozilla.org/show_bug.cgi?id=245066

   5. It may be possible to import an invalid CA certificate with a
   Domain Name the same as that of the built-in CA root certificates.
   This could cause a denial of service (DOS) to SSL pages.

   This issue is described in the following document:

     * [6]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0758

   6. By using a NULL character (%00) in a FTP URL, Mozilla can be
   confused into opening a resource as a different MIME type. This may
   allow an unprivileged user to gain the privileges of a local user
   running Mozilla.

   This issue is described in the following document:

     * [7]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0760

   7. Mozilla may allow a malicious website to inject content into a
   frame. This flaw is also known as the "frame injection" vulnerability.

   This issue is described in the following document:

     * [8]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0718

   8. Mozilla may allow a malicious webpage to use a redirect sequence to
   spoof the security lock icon thus causing the webpage to appear to be
   encrypted.

   This issue is described in the following document:

     * [9]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0761

   9. Mozilla may allow malicious websites to install arbitrary
   extensions by using interactive events to manipulate the "XP Install
   Security" dialog box.

   This issue is described in the following document:

     * [10]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-076
       2

   10. Mozilla contains a caching flaw which may allow malicious websites
   to spoof certificates of trusted websites via redirects and Javascript
   that uses the "onunload" method.

   This issue is described in the following document:

     * [11]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-076
       3

   11. Mozilla contains a flaw that allows malicious websites to hijack
   the user interface via the "chrome" flag and XML User Interface
   Language (XUL) files.

   This issue is described in the following document:

     * [12]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-076
       4

   12. Mozilla may allow a malicious website to spoof Mozilla into
   thinking it was accessing a trusted host. This is due to a flaw when
   verifying a certificate where as the hostname checked is not the fully
   qualified domain name (FQDN).

   This issue is described in the following document:

     * [13]http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-076
       5 

   13. Mozilla contains a flaw that could allow malicious javascript to
   obtain or modify sensitive information from secure sites by dragging
   links onto other frames or pages.

   This issue is described in the following document:

     * [14]https://bugzilla.mozilla.org/show_bug.cgi?id=250862 

   14. An integer overflow exists that may allow a remote unprivileged
   user to execute arbitrary code with the privileges of a local user
   when that local user has loaded an extremely wide Bitmap (.bmp) format
   image file supplied by an untrusted user.

   This issue is described in the following document:

     * [15]https://bugzilla.mozilla.org/show_bug.cgi?id=255067 

   15. Mozilla contains a flaw that could allow malicious javascript code
   to read and write sensitive data that the user might have copied into
   the clipboard.

   This issue is described in the following document:

     * [16]https://bugzilla.mozilla.org/show_bug.cgi?id=257523

   16. A heap overflow exists in the "send page" function that may allow
   a remote unprivileged user the ability to execute arbitrary code with
   the privileges of a local user when that user attempts to forward
   content to others.

   This issue is described in the following document:

     * [17]https://bugzilla.mozilla.org/show_bug.cgi?id=258005

   17. A buffer overflow exists when displaying VCards that may allow a
   remote unprivileged user the ability to execute arbitrary code with
   the privileges of a local user.

   This issue is described in the following document:

     * [18]https://bugzilla.mozilla.org/show_bug.cgi?id=257314

   2. Contributing Factors These issues can occur on the following
   platforms:

   SPARC Platform

     * Solaris 8
     * Solaris 9

   x86 Platform

     * Solaris 8
     * Solaris 9

   Linux

     * Sun Java Desktop System (JDS) 2003
     * Sun Java Desktop System (JDS) Release 2 without the updated RPMs
       (patch-118492-02)

   Note: Solaris 7 is not affected by these issues.

   The described issues only occur with the following Mozilla versions:

     * mozilla-1.4.1-221 or earlier
     * mozilla-mail-1.4.1-223 or earlier

   To determine the version of Mozilla installed on a system, the
   following command can be used:

    % /usr/sfw/bin/mozilla -version
      Mozilla 1.4, (Sun Java Desktop System; Solaris), build 2004041404


   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 /usr/lib/mozilla-1.4/components/libmsgnews.so
    mozilla-1.4.1-221
    mozilla-mail-1.4.1-223

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