Thank you for using Ubuntu and taking the time to report a bug. The only way to protect your data from a live cd or other means is to encrypt it. Ubuntu users have various options for encrypting their data, including Encrypted LVM via the alternate installer CD and Ecryptfs (https://wiki.ubuntu.com/EncryptedPrivateDirectory). Integrated ecryptfs has been greatly improved in the upcoming 8.10 release, though good support is also included in earlier releases, such as Ubuntu 8.04.
There are plans to investigate using Ecryptfs in the default install in upcoming releases.
