Debian DLA-2651-1 : python-django security update

high Nessus Plugin ID 149339

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was potential directory-traversal vulnerability in Django, a popular Python-based web development framework.

The MultiPartParser, UploadedFile and FieldFile classes allowed directory-traversal via uploaded files with suitably crafted file names. In order to mitigate this risk, stricter basename and path sanitation is now applied. Specifically, empty file names and paths with dot segments are rejected.

For Debian 9 'Stretch', this problem has been fixed in version 1:1.10.7-2+deb9u13.

We recommend that you upgrade your python-django packages.

For the detailed security status of python-django please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/python-django

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
