Vulnerable code:

def true_path(path):

This is going public in a few hours.
Suggested fix from Barry Warsaw:

=======================================
SLASH = '/'

def true_path(path):
    "Ensure that the path is safe by removing .."
    parts = [x for x in path.split(SLASH) if x not in ('.', '..')]
    return SLASH.join(parts)[1:]
=============================================

langthang: please commit new patched ebuilds. Mailman won't release a new version until Friday.
