==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10

Summary:

Fraudulent security certificates could allow sensitive information to
be exposed when accessing the Internet.

Software Description:

to perform a man-in-the-middle attack, this flaw could be exploited to
alter or compromise confidential information.

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
  python-ubuntuone-client         3.0.0-0ubuntu1.1
