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 - Ubuntu 8.04 LTS Summary: An attacker could trick APT into installing altered packages. Software Description: - apt: Advanced front-end for dpkg Details: Georgi Guninski discovered that APT did not properly validate imported keyrings via apt-key net-update. USN-1475-1 added additional verification for imported keyrings, but it was insufficient. 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 12.04 LTS: Ubuntu 11.10: Ubuntu 11.04: Ubuntu 10.04 LTS: Ubuntu 8.04 LTS: In general, a standard system update will make all the necessary changes.
