Detail

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

- Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10

Summary:

An attacker could trick Software Center into installing altered packages and repositories or exposing sensitive information over the network.

Software Description: - software-center: Utility for browsing, installing, and removing software

Details:

David B. discovered that Software Center incorrectly validated server certificates when performing secure connections. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information or install altered packages and repositories.

Update instructions:

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

Ubuntu 11.10:
software-center 5.0.2ubuntu0.1

Ubuntu 11.04:
software-center 4.0.5ubuntu0.1

Ubuntu 10.10:
software-center 3.0.10ubuntu0.1

In general, a standard system update will make all the necessary changes.
