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

high Nessus Plugin ID 56115

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

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