An attacker can use this to perform denial of service attacks (100% CPU consumption) due to bad backtracking via a specially crafted email address or URL which is validated by the django forms library. python-django in the oldstable distribution (etch), is not affected by this problem. For the stable distribution (lenny), this problem has been fixed in version 1.0.2-1+lenny2. For the testing distribution (squeeze), this problem will be fixed soon. For the unstable distribution (sid), this problem has been fixed in version 1.1.1-1. We recommend that you upgrade your python-django packages.
