Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

Django project reports :

Django's forms library includes field types which perform
regular-expression-based validation of email addresses and URLs.
Certain addresses/URLs could trigger a pathological performance case
in these regular expression, resulting in the server process/thread
becoming unresponsive, and consuming excessive CPU over an extended
period of time. If deliberately triggered, this could result in an
effectively denial-of-service attack.
