Summary:
Fraudulent security certificates could allow sensitive information to
be exposed when accessing the Internet.
Software Description:

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.
