Detail

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

- Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS

Summary:

Software Properties could be tricked into installing arbitrary PPA GPG keys.

Software Description: - software-properties: manage the repositories that you install software from

Details:

David Black discovered that Software Properties incorrectly validated server certificates when performing secure connections to download PPA GPG key fingerprints. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to install altered package repository GPG keys.

Update instructions:

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

Ubuntu 11.10:
python-software-properties 0.81.13.3

Ubuntu 11.04:
python-software-properties 0.80.9.1

Ubuntu 10.10:
python-software-properties 0.76.7.1

Ubuntu 10.04 LTS:
python-software-properties 0.75.10.2

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