I am not a stupid man.  

I hold a Bachelor of Science, and a doctorate of Law.  I passed the test for 
Mensa, and am even an AKC judge.  I passed the notary exam, have argued before 
the California Supreme Court on a number of occasions.  I am admitted to 
Federal Tax Court, The Court of Military Appeals, and have had over 200 jury 
verdicts.  I have won appeals in over 30 cases before the Court of Appeals, and 
have tried cases in four states.  I was admitted to the Magic Castle, and have 
won awards for performing on stage as a magician.
 
With that being said, I have no idea what Zoe is saying. I know it is English, 
and I know I can use a computer, but am I the only person who can't decipher 
that language.
 
One the other hand, do I need to know?
 
Evan

With details of the new POODLE attack on SSLv3 now public, browser vendors are 
in the process of planning how they’re going to address the issue in their 
products in a way that doesn’t break the Internet for millions of u
sers but still provides protection.

The attack, which was disclosed by a trio of Google security researchers on 
Tuesday, allows an attacker on the same network as a victim to decrypt 
sensitive 
data that’s protected by SSLv3 encryption. It can be executed in
 the background and takes advantage of the fact that when a client tries to 
establish a secure connection to a server and fails, the server will attempt to 
make the connection using a different protocol, a process known a
s falling back. An attacker can force an unsuccessful connection and make the 
server use SSLv3, and then execute the attack.

Officials at Mozilla said that although Firefox only uses SSLv3 for about 0.3 
percent of 
transactions globally, the POODLE attack still represents a significant threat 
to users. The 
company is planning to remove the vulnerable protocol from Firefox by the end 
of 
next month.
“SSLv3 will be disabled by default in Firefox 34, which will be released on 
Nov 
25.”

“SSLv3 will be disabled by default in Firefox 34, which will be released on 
Nov 
25. The code to 
disable it is landing today in Nightly, and will be promoted to Aurora and Beta 
in the next few 
weeks. This timing is intended to allow website operators some time to upgrade 
any servers that 
still rely on SSLv3,” Richard Barnes of Mozilla said in a blog post.

“As an additional precaution, Firefox 35 will support a generic TLS downgrade 
protection mechanism known as SCSV. If this is supported by the server, it 
prevents attacks that rely on insecure fallback.”

Google security officials said that Chrome has supported the SCSV mechanism 
since February, but warned that disabling SSLv3 will cause problems for site 
owners who still support the protocol.

“Disabling SSL 3.0 support, or CBC-mode ciphers with SSL 3.0, is sufficient to 
mitigate this issue, but presents significant compatibility problems, even 
today. Therefore our recommended response is to support TLS_FALLBAC
K_SCSV. This is a mechanism that solves the problems caused by retrying failed 
connections and thus prevents attackers from inducing browsers to use SSL 3.0. 
It also prevents downgrades from TLS 1.2 to 1.1 or 1.0 and so m
ay help prevent future attacks,” said Bodo Möller, one of the Google 
researchers 
who developed the attack.

“Google Chrome and our servers have supported TLS_FALLBACK_SCSV since February 
and thus we have good evidence that it can be used without compatibility 
problems. Additionally, Google Chrome will begin testing changes toda
y that disable the fallback to SSL 3.0. This change will break some sites and 
those sites will need to be updated quickly.”

Microsoft issued an advisory about the POODLE attack on Tuesday but didn’t 
announce any 
specific plans for disabling the protocol in Windows or Internet Explorer. IE 
6, 
an ancient version 
of the company’s browser, is the only major browser that doesn’t support 
anything newer than 
SSLv3.

“This is an industry-wide vulnerability affecting the SSL 3.0 protocol itself 
and is not specific to 
the Windows operating system. All supported versions of Microsoft Windows 
implement this 
protocol and are affected by this vulnerability. Microsoft is not aware of 
attacks that try to use 
the reported vulnerability at this time. Considering the attack scenario, this 
vulnerability is not 
considered high risk to customers,” Microsoft’s advisory says.
