Arch Linux Security Advisory ASA-201607-10
=========================================
Severity: Medium
Date    : 2016-07-22
CVE-ID  : CVE-2016-6186
Package : python-django
Type    : cross-site scripting
Remote  : Yes
Link    : https://wiki.archlinux.org/title/CVE

Summary
======
The package python-django before version 1.9.8-1 is vulnerable to
cross-site scripting.

Resolution
=========
Upgrade to 1.9.8-1.

# pacman -Syu "python-django>=1.9.8-1"

The problem has been fixed upstream in version 1.9.8.

Workaround
=========
None.

Description
==========
Unsafe usage of JavaScript's Element.innerHTML could result in XSS in
the admin's add/change related popup. Element.textContent is now used to
prevent execution of the data.

The debug view also used innerHTML. Although a security issue wasn't
identified there, out of an abundance of caution it's also updated to
use textContent.

Impact
=====
An attacker is able to execute arbitrary javascript code in the client's
browser by inserting code in the admin's add/change related popup.
