Description Martin Prpič 2015-07-07 07:49:16 UTC
The following flaw was found in Django:

'django.core.validators.URLValidator' included a regular expression that was extremely slow to evaluate against certain invalid inputs. This regular expression has been simplified and optimized.

This flaw has been fixed in Django version 1.8.3.

Acknowledgements:

Red Hat would like to thank the upstream Django project for reporting this issue.
