Just when you thought it was safe to go back in the water...

...well, go back surfing anyway ;) 

For those of you that have recently switched to Mozilla or Firefox / 
Thunderbird on Windows there's a recently discovered security bug :( 

>From http://mozilla.org/security/shell.html - more details & links to 
patches & latest, fixed, versions are there too.

What Mozilla users should know about the shell: protocol security issue

On July 7 (yesterday) a security vulnerability affecting browsers for the 
Windows operating system was posted to Full Disclosure, a public security 
mailing list. On the same day, the Mozilla security team confirmed the 
report of this security issue affecting the Mozilla Application Suite, 
Firefox, and Thunderbird and discussed and developed the fix at Bugzilla 
bug 250180. We have confirmed that the bug affects only users of 
Microsoft's Windows operating system. The issue does not affect Linux or 
Macintosh users.

Today, the Mozilla team released a configuration change which resolves this 
problem by explicitly disabling the use of the shell: external protocol 
handler. The fix is available in two forms. The first is a small download 
which will make this configuration adjustment for the user. The second fix 
is to install the newest full release of each of these products. 
Instructions on administering these changes can be found below.
