Detail

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

- Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 11.04 - 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:

It was discovered that the apt-add-repository tool incorrectly validated PPA GPG keys when importing from a keyserver. 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 12.04 LTS:
python-software-properties 0.82.7.3

Ubuntu 11.10:
python-software-properties 0.81.13.5

Ubuntu 11.04:
python-software-properties 0.80.9.2

Ubuntu 10.04 LTS:
python-software-properties 0.75.10.3

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