software-center vulnerability

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

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


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.

Ubuntu 11.10: software-center 5.0.2ubuntu0.1

Ubuntu 11.04: software-center 4.0.5ubuntu0.1
