OVERVIEW:

       A research paper from Microsoft has identified security risks 
       affecting all major browsers and many websites when communicating
       via a proxy server. [1]


IMPACT:

       Microsoft Internet Explorer, Opera, and Google Chrome are open to 
       man-in-the-middle attacks when displaying a certificate for a CONNECT 
       response page from a proxy server, spoofing an arbitrary https site by 
       letting a browser obtain a valid certificate, then sending the browser 
       a crafted 502 response page upon a subsequent request.

       Apple Safari, however, does not require a cached certificate to 
       display a padlock icon for an https site when given a crafted CONNECT 
       response page.

       The vulnerabilities are:

       CVE-2009-2069 Microsoft Internet Explorer before 8 
       CVE-2009-2070 Opera
       CVE-2009-2071 Google Chrome before 1.0.154.53
       CVE-2009-2072 Apple Safari
       

       Microsoft Internet Explorer, Apple Safari, Opera and Google Chrome 
       are vulnerable to an "SSL tampering attack", whereby the browser is 
       compromised via a man-in-the-middle attack through the injection of 
       arbitrary web script by modifying a CONNECT response.

       The vulnerabilities are:

       CVE-2009-2057 Microsoft Internet Explorer before 8
       CVE-2009-2058 Apple Safari before 3.2.2
       CVE-2009-2059 Opera, possibly before 9.25
       CVE-2009-2060 Google Chrome before 1.0.154.53

       Mozilla Firefox, Apple Safari and Opera, are vulnerable to a 
       man-in-the-middle attack via the injection of arbitrary web script 
       into an https site by modifying a CONNECT response.
       
       The vulnerabilities are:

       CVE-2009-2061 Mozilla Firefox before 3.0.10
       CVE-2009-2062 Apple Safari before 3.2.2
       CVE-2009-2063 Opera, possibly before 9.25

       
       Mozilla Firefox, Opera, Microsoft Internet Explorer, Google Chrome 
       and Apple Safari are vulnerable to a man-in-the-middle attack by
       the injection of arbitrary web script, in an https site, by modifying 
       an http page to include an https iframe that references a script file 
       on an http site.

       The vulnerabilities are:

       CVE-2009-2064 Microsoft Internet Explorer 8
       CVE-2009-2065 Mozilla Firefox 3.0.10, and possibly other versions
       CVE-2009-2066 Apple Safari
       CVE-2009-2067 Opera
       CVE-2009-2068 Google Chrome


MITIGATION:

       Many of these browsers have patches available and some are in the 
       process of being patched. Please refer to the vendors' websites for
       updates.

       Fixes are available for the following:

       CVE-2009-2058 Apple Safari before 3.2.2
       CVE-2009-2059 Opera, possibly before 9.25
       CVE-2009-2060 Google Chrome before 1.0.154.53
       CVE-2009-2061 Mozilla Firefox before 3.0.10
       CVE-2009-2062 Apple Safari before 3.2.2
       CVE-2009-2063 Opera, possibly before 9.25
       CVE-2009-2065 Mozilla Firefox 3.0.10, and possibly other versions
       CVE-2009-2071 Google Chrome before 1.0.154.53

       Please see the Microsoft Research page for further details on the 
       investigation of this vulnerability. [1]
       Further details regarding the individual CVEs can be found on the 
       NIST website. [2]
