The urllib and urllib2 modules in Python 2.x before 2.7.2 and 3.x before
3.2.1 process Location headers that specify redirection to file: URLs,
which makes it easier for remote attackers to obtain sensitive information
or cause a denial of service (resource consumption) via a crafted URL, as
demonstrated by the file:///etc/passwd and file:///dev/zero URLs.
