Ubuntu alert USN-1284-2 (update-manager)
========================================================================== Ubuntu Security Notice USN-1284-2 February 16, 2012 update-manager regression ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS Summary: USN-1284-1 introduced a regression in Update Manager. Software Description: - update-manager: GNOME application that manages apt updates Details: USN-1284-1 fixed vulnerabilities in Update Manager. One of the fixes introduced a regression for Kubuntu users attempting to upgrade to a newer Ubuntu release. This update fixes the problem. We apologize for the inconvenience. Original advisory details: David Black discovered that Update Manager incorrectly extracted the downloaded upgrade tarball before verifying its GPG signature. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could potentially be used to replace arbitrary files. (CVE-2011-3152) David Black discovered that Update Manager created a temporary directory in an insecure fashion. A local attacker could possibly use this flaw to read the XAUTHORITY file of the user performing the upgrade. (CVE-2011-3154) This update also adds a hotfix to Update Notifier to handle cases where the upgrade is being performed from CD media. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: update-manager-core 1:0.152.25.8 Ubuntu 11.04: update-manager-core 1:0.150.5.2 Ubuntu 10.10: update-manager-core 1:0.142.23.2 Ubuntu 10.04 LTS: update-manager-core 1:0.134.11.2 Ubuntu 8.04 LTS: update-manager-core 1:0.87.33 In general, a standard system update will make all the necessary changes.
