I wasn't going to go into this, but since you request more details,
here they are.  Being from the PR industry, this warning from CERT
positively reeks of attack PR.  I guess they've been damaged by...
some corrupting force - use your imagination as to what it might be.
Notice how many times they hammer in phrases like:

"Mozilla products fail to....",

"Mozilla products are vulnerable to....",

"Mozilla products contain multiple vulnerabilities...."

- etc. etc.

I just mentioned it to the list for those of us who are using FireFox
and/or Thunderbird - who are generally interested in paying attention
to security updates.

As for the CERT letter - here's the full text for your reading
pleasure.  From other sources, I head that it affects our beloved
product from Brand-W as well, interesting that there's no mention of
that in the CERT letter.....


National Cyber Alert System

                Technical Cyber Security Alert TA06-208A


Mozilla Products Contain Multiple Vulnerabilities

  Original release date: July 27, 2006
  Last revised: --
  Source: US-CERT


Systems Affected

    * Mozilla SeaMonkey
    * Mozilla Firefox
    * Mozilla Thunderbird

  Any products based on Mozilla components, specifically Gecko, may also
  be affected.


Overview

  The Mozilla web browser and derived products contain several
  vulnerabilities, the most serious of which could allow a remote
  attacker to execute arbitrary code on an affected system.


I. Description

  Several vulnerabilities have been reported in the Mozilla web browser
  and derived products. More detailed information is available in the
  individual vulnerability notes, including the following:


  VU#476724 - Mozilla products fail to properly handle frame references

  Mozilla products fail to properly handle frame or window references.
  This may allow a remote attacker to execute arbitrary code on a
  vulnerable system.
  (CVE-2006-3801)


  VU#670060 - Mozilla fails to properly release JavaScript references

  Mozilla products fail to properly release memory. This vulnerability
  may allow a remote attacker to execute code on a vulnerable system.
  (CVE-2006-3677)


  VU#239124 - Mozilla fails to properly handle simultaneous XPCOM events

  Mozilla products are vulnerable to memory corruption via simultaneous
  XPCOM events. This may allow a remote attacker to execute arbitrary
  code on a vulnerable system.
  (CVE-2006-3113)


  VU#265964 - Mozilla products contain a race condition

  Mozilla products contain a race condition. This vulnerability may
  allow a remote attacker to execute code on a vulnerable system.
  (CVE-2006-3803)


  VU#897540 - Mozilla products VCard attachment buffer overflow

  Mozilla products fail to properly handle malformed VCard attachments,
  allowing a buffer overflow to occur. This vulnerability may allow a
  remote attacker to execute arbitrary code on a vulnerable system.
  (CVE-2006-3804)


  VU#876420 - Mozilla fails to properly handle garbage collection

  The Mozilla JavaScript engine fails to properly perform garbage
  collection, which may allow a remote attacker to execute arbitrary
  code on a vulnerable system.
  (CVE-2006-3805)


  VU#655892 - Mozilla JavaScript engine contains multiple integer
  overflows

  The Mozilla JavaScript engine contains multiple integer overflows.
  This vulnerability may allow a remote attacker to execute arbitrary
  code on a vulnerable system.
  (CVE-2006-3806)


  VU#687396 - Mozilla products fail to properly validate JavaScript
  constructors

  Mozilla products fail to properly validate references returned by
  JavaScript constructors. This vulnerability may allow a remote
  attacker to execute arbitrary code on a vulnerable system.
  (CVE-2006-3807)


  VU#527676 - Mozilla contains multiple memory corruption
  vulnerabilities

  Mozilla products contain multiple vulnerabilities that can cause
  memory corruption. This may allow a remote attacker to execute
  arbitrary code on a vulnerable system.
  (CVE-2006-3811)


II. Impact

  A remote, unauthenticated attacker could execute arbitrary code on a
  vulnerable system. An attacker may also be able to cause the
  vulnerable application to crash.


III. Solution

Upgrade

  Upgrade to Mozilla Firefox 1.5.0.5, Mozilla Thunderbird 1.5.0.5, or
  SeaMonkey 1.0.3.

Disable JavaScript and Java

  These vulnerabilities can be mitigated by disabling JavaScript and
  Java in all affected products. Instructions for disabling Java in
  Firefox can be found in the "Securing Your Web Browser" document.
