Ubuntu 10.04 LTS / 10.10 / 11.04 : qt4-x11 vulnerability (USN-1197-6)

high Nessus Plugin ID 56279

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

USN-1197-1 and USN-1197-3 addressed an issue in Firefox and Xulrunner pertaining to the Dutch Certificate Authority DigiNotar mis-issuing fraudulent certificates. This update provides an update for Qt that blacklists the known fraudulent certificates.

USN-1197-1

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.

USN-1197-3

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.

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 libqt4-network package.
