Ubuntu 10.04 LTS / 10.10 / 11.04 : firefox, xulrunner-1.9.2 vulnerability (USN-1197-3)

Ubuntu Security Notice (C) 2011-2013 Canonical, Inc. / NASL script (C) 2011-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

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.

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.

Solution :

Update the affected firefox and / or xulrunner-1.9.2 packages.

Risk factor :

High
