Yes, Dave these are indeed problematic. Apparently, the browsers affected
include Internet Explorer 6 and Mozilla Firefox 2. In addition, IE 7 suffers
from vulnerabilities that include system access from remote hacking which
really is bad.


Here is a secunia.com warning showing if affects a fully updated IE 6

http://secunia.com/advisories/30857/

and one in a fully updated Internet Explorer 7

http://secunia.com/advisories/24314/

and don't forget about this one in IE 7 that allows for system access

http://secunia.com/advisories/30851/

last updated July 9, 2008 -- let us all get with the program here folks

here is one from a fully updated Firefox 2.x

http://secunia.com/advisories/27907/

Mozilla Firefox 3 takes it up a notch with all 3 current vulnerabilities
patched but if you want to use Mozilla Firefox 2 add-ons that my dad, Ivan
really enjoys then for now you are stuck with using Mozilla Firefox 2 because
many of the good ad-ons do not yet support Mozilla Firefox 3. Thus, this all
leads to trade off's and balances between external security of Vista,
internal safety of 98 Second Edition and using open source technologies to
help maintain a safety and security balance. Finally, Ubuntu Linux comes
into play as being very safe and secure but the compatibility is still
lacking for many users so this must be taken into account as well but if you
want an operating system that is great for emailing and web surfing then
Ubuntu Linux should be your number 1 choice.

OT - for Dan. :)

I've now noticed that you have popped in to Jenn's BB. I've left you a PM

You may like to look at Jenn's *web* site - here:- http://pqlr.org/

I was touched by her story "in Grandma's Attic" which you'll find here:-
http://pqlr.org/writing.html

I found it quite by accident long before being directed (from above?!!) to
her small BB.

I hope you'll find time to join us!

Dave

I don`t get, why you have started to talk about vulnerabilities in browsers,
when the article was about CSRF...



Yes, these vulnerabilities are nasty, but not worse than SQL injection or
remote/local file including...



No, register is not right about nonexistence of CSRF/XSS worm. Try to google
for XSS worm...



I liked the idea of separate browsers :))) had a lot of fun :) You can also
use separate computers (which are connected to each other) to access
Internet and local network :)



>In addition, IE 7 suffers from vulnerabilities that include system access
>from remote hacking which really is bad.

Currently there are no publicly known unpatched "vulnerabilities that
include system access from remote hacking" in both IE 6 and 7, Firefox or
Opera.
