More information:

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+deb7u2.

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.
