Title:	Debian: Security Advisory (DLA-1872-1)
Summary:	The remote host is missing an update for the Debian 'python-django' package(s) announced via the DLA-1872-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'python-django' package(s) announced via the DLA-1872-1 advisory. Vulnerability Insight: It was discovered that there were two vulnerabilities in the Django web development framework: CVE-2019-14232 Prevent a possible denial-of-service in django.utils.text.Truncator. If django.utils.text.Truncator's chars() and words() methods were passed the html=True argument, they were extremely slow to evaluate certain inputs due to a catastrophic backtracking vulnerability in a regular expression. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which were thus vulnerable. The regular expressions used by Truncator have been simplified in order to avoid potential backtracking issues. As a consequence, trailing punctuation may now at times be included in the truncated output. CVE-2019-14233 Prevent a possible denial-of-service in strip_tags(). Due to the behavior of the underlying HTMLParser, django.utils.html.strip_tags() would be extremely slow to evaluate certain inputs containing large sequences of nested incomplete HTML entities. The strip_tags() method is used to implement the corresponding striptags template filter, which was thus also vulnerable. strip_tags() now avoids recursive calls to HTMLParser when progress removing tags, but necessarily incomplete HTML entities, stops being made. Remember that absolutely NO guarantee is provided about the results of strip_tags() being HTML safe. So NEVER mark safe the result of a strip_tags() call without escaping it first, for example with django.utils.html.escape(). For Debian 8 Jessie, these problems have been fixed in version 1.7.11-1+deb8u7. We recommend that you upgrade your python-django packages.
