Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS

Summary:

A certificate authority issued fraudulent certificates.

Software Description: - 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 Staat der Nederlanden root certificates.

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 "man 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 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:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.04:
firefox 6.0.2+build2+nobinonly-0ubuntu0.11.04.1

Ubuntu 10.10:
firefox 3.6.22+build2+nobinonly-0ubuntu0.10.10.1
xulrunner-1.9.2 1.9.2.22+build2+nobinonly-0ubuntu0.10.10.1

Ubuntu 10.04 LTS:
firefox 3.6.22+build2+nobinonly-0ubuntu0.10.04.1
xulrunner-1.9.2 1.9.2.22+build2+nobinonly-0ubuntu0.10.04.1

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