Title: USN-1283-1 -- APT vulnerability
Description: apt: Advanced front-end for dpkg Details: It was discovered that APT incorrectly handled the Verify-Host configuration option. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could potentially be used to steal repository credentials. This issue only affected Ubuntu 10.04 LTS and 10.10. USN-1215-1 fixed a vulnerability in APT by disabling the apt-key net-update option. This update re-enables the option with corrected verification. Original advisory APT could be made to expose sensitive information over the network.
