Ubuntu 10.04 LTS / 10.10 / 11.04 : firefox, xulrunner-1.9.2 vulnerability (USN-1197-1)

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 :

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
