USN-1197-3: Firefox and Xulrunner vulnerability | Ubuntu security notices

Packages

firefox - Mozilla Open Source web browser
xulrunner-1.9.2 - Mozilla Gecko runtime environment

Details

USN-1197-1 partially addressed an issue with Dutch Certificate Authority
DigiNotar mis-issuing fraudulent certificates. This update actively
distrusts the DigiNotar root certificate as well as several intermediary
certificates. Also included in this list of distrusted certificates are the
“PKIOverheid” (PKIGovernment) intermediates under DigiNotar’s control that
did not chain to DigiNotar’s root and were not previously blocked.

Original advisory details:

It was discovered that Dutch Certificate Authority DigiNotar, had
mis-issued multiple fraudulent certificates. These certificates could allow
an attacker to perform a “machine-in-the-middle” (MITM) attack which would make
the user believe their connection is secure, but is actually being
monitored.

For the protection of its users, Mozilla has removed the DigiNotar
certificate. Sites using certificates issued by DigiNotar will need to seek
another certificate...

another certificate vendor.

We are currently aware of a regression that blocks one of two Staat der
Nederlanden root certificates which are believed to still be secure. This
regression is being tracked at https://launchpad.net/bugs/838322.

Update instructions

After a standard system upgrade you need to restart Firefox and any applications that use Xulrunner to effect the necessary changes.
