I tried epiphany, that browser doesn't even give a warning when a cert
is invalid. One week ago the cert for GNOME bugzilla was expired,
Firefox couldn't add an exception, making it unable to visit
bugs.gnome.org, but epiphany just shows the website without any warning.
When I check a DigiNotar signed website, Epiphany shows a broken lock in
the address bar, so though it's SSL, it says the security is broken.

Heise is wrong IMHO. When the DigiNotar hack was made public, all
browser companies issued updates. Both Microsoft and Mozilla added
checks to their browsers to see if a cert originates from "Staat der
Nederlanden CA" so the cert would get accepted as valid. Now that Fox IT
uncovered a report about the security at DigiNotar and that not any cert
ever issued by this company should be trusted, Mozilla and Microsoft
decided to remove that exception and just disable all DigiNotar
I pulled in this update through Windows Update this morning, I had to
reboot for it (Windows XP). On Windows XP you don't have to reboot for a
base certificate update, so this is an update that touches code instead
of some certificate store.
