Create a malicious .tar file with entries containing absolute or relative paths and the tarfile module happily uses them as is without sanity checking. filed in response to http://bugs.python.org/issue6972 which fixed the zipfile module for this. I'm attaching an example tar file to demonstrate this (safely) but much worse things could obviously be done.
