Software 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. (CVE-2011-3634) 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 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. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.04: apt 0.8.13.2ubuntu4.3 Ubuntu 10.10: apt 0.8.3ubuntu7.3 Ubuntu 10.04 LTS: apt 0.7.25.3ubuntu9.9 Ubuntu 8.04 LTS: apt 0.7.9ubuntu17.4 In general, a standard system update will make all the necessary changes.
