UPR Security Notice UPRSN-08_03 January 16, 2009 several vulnerabilities ########################################################### Ubuntu Privacy Remix (UPR), based on Ubuntu 8.04 (LTS), is a live, read-only CD that seals off your private data from the outside world to offer protection against spying measures such as the german „Bundestrojaner“, with which the German government and federal police tries to spy on its citizens. UPR does this using encryption and isolation methods. This method of booting off a read-only CD provides a isolated and unmodifiable system that is exceedingly difficult to compromise by spyware. The following security issues affect the "Ubuntu Privacy Remix" releases prior 8.04_r3. Ubuntu Privacy Remix 8.04_r1 can be downloaded from https://www.privacy-cd.org/ A. UPR-specific - --------------- 1. New feature to overwrite memory on shutdown which prevents that remains of the UPR system (e.g. encryption keys) are still readable from RAM after reboot from a compromised local operating system (see article “The Problem of „Cold Boot Attacks“” for details: https://www.privacy-cd.org/index.php?option=com_content&view=article&id=70%3Acold-boot-angriffe&catid=19%3Afeatures&Itemid=35&lang=en). B. Security Updates adopted from Ubuntu - --------------------------------------- All packages with security-fixes in Ubuntu 8.04 until 02/10/2009 have been updated. Among others the sources, the UPR-Kernel ist based on, were updated to Ubuntu source-package 2.6.24-23.
