Description:	Summary: The remote host is missing an update for the 'update-manager' package(s) announced via the USN-1284-2 advisory. Vulnerability Insight: 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 machine-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. Affected Software/OS: 'update-manager' package(s) on Ubuntu 8.04, Ubuntu 10.04, Ubuntu 10.10, Ubuntu 11.04, Ubuntu 11.10. Solution: Please install the updated package(s).
