Ubuntu Security Notice USN-1465-3
June 06, 2012
ubuntuone-client regression
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Summary:
Fraudulent security certificates could allow sensitive information to
be exposed when accessing the Internet.
Software Description:
- ubuntuone-client: Ubuntu One client
Details:
USN-1465-1 fixed vulnerabilities in Ubuntu One Client. The update failed to
install on certain Ubuntu 10.04 LTS systems that had a legacy Python 2.5
package installed. This update fixes the problem.
We apologize for the inconvenience.
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 10.04 LTS:
python-ubuntuone-client 1.2.2-0ubuntu2.3
In general, a standard system update will make all the necessary changes.
