Ubuntu Update for Linux kernel vulnerabilities USN-1215-1
Please Install the Updated Packages.
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.
apt on Ubuntu 11.04 , Ubuntu 10.10 , Ubuntu 10.04 LTS , Ubuntu 8.04 LTS
