Detail

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

- Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS

Summary:

An attacker could trick APT into installing altered packages.

Software Description: - apt: Advanced front-end for dpkg

Details:

It was discovered that the apt-key utility incorrectly verified GPG keys when downloaded via the net-update option. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could potentially be used to install altered packages. This update corrects the issue by disabling the net-update option completely. A future update will re-enable the option with corrected verification.

Update instructions:

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

Ubuntu 11.04:
apt 0.8.13.2ubuntu4.2

Ubuntu 10.10:
apt 0.8.3ubuntu7.2

Ubuntu 10.04 LTS:
apt 0.7.25.3ubuntu9.7

Ubuntu 8.04 LTS:
apt 0.7.9ubuntu17.3

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