========================================================================== Ubuntu Security Notice USN-1465-2 June 06, 2012
ubuntuone-storage-protocol update ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.04 LTS
Summary:
Fraudulent security certificates could allow sensitive information to be exposed when accessing the Internet.
Software Description: - ubuntuone-storage-protocol: Python library for Ubuntu One file storage and sharing service
Details:
USN-1465-1 fixed a vulnerability in the Ubuntu One Client. This update adds a required fix to the Ubuntu One storage protocol library.
Original advisory details:
It was discovered that the Ubuntu One Client incorrectly validated server certificates when using HTTPS connections. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to alter or compromise confidential information.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04 LTS: python-ubuntuone-storageprotocol 3.0.0-0ubuntu1.1
Ubuntu 11.10: python-ubuntuone-storageprotocol 2.0.1-0ubuntu1.1
Ubuntu 11.04: python-ubuntuone-storageprotocol 1.6.1-0ubuntu1.2
Ubuntu 10.04 LTS: python-ubuntuone-storageprotocol 1.2.0-0ubuntu1.1
In general, a standard system update will make all the necessary changes.
