Ubuntu 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : ubuntuone-client vulnerability (USN-1465-1)

High Nessus Plugin ID 59396


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


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.

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.


Update the affected python-ubuntuone-client package.
