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
âBundestrojanerâ, 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
 âThe Problem of âCold Boot Attacksââ 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.
