CVE-2018-7536: Denial-of-service possibility in ``urlize`` and ``urlizetrunc`` template filters
|
|
|
|
|
===============================================================================================
|
|
|
|
|
|
|
|
|
|
The ``django.utils.html.urlize()`` function was extremely slow to evaluate
|
|
|
|
|
certain inputs due to a catastrophic backtracking vulnerability in a regular
|
|
|
|
|
expression. The ``urlize()`` function is used to implement the ``urlize`` and
|
|
|
|
|
``urlizetrunc`` template filters, which were thus vulnerable.
|
|
|
|
|
|
|
|
|
|
The problematic regular expression is replaced with parsing logic that behaves
|
|
|
|
|
similarly.
