    Nick Brunn reported a possible cross-site scripting vulnerability in
    python-django, a high-level Python web development framework.
    
    The is_safe_url utility function used to validate that a used URL is on
    the current host to avoid potentially dangerous redirects from
    maliciously-constructed querystrings, worked as intended for HTTP and
    HTTPS URLs, but permitted redirects to other schemes, such as
    javascript:.
    
    The is_safe_url function has been modified to properly recognize and
    reject URLs which specify a scheme other than HTTP or HTTPS, to prevent
    cross-site scripting attacks through redirecting to other schemes.
    
    For the oldstable distribution (squeeze), this problem has been fixed in
    version 1.2.3-3+squeeze6.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 1.4.5-1+deb7u1.
    
    For the testing distribution (jessie) and the unstable distribution
    (sid), this problem has been fixed in version 1.5.2-1.
    
    We recommend that you upgrade your python-django packages.
