Additional Changes :

This update also fixes several bugs and adds various enhancements.
Documentation for these changes is available from the Release Notes document linked to in the References section.

It was discovered that Django incorrectly handled numeric redirect URLs. A remote attacker could possibly use this issue to perform XSS attacks, and to use a Django server as an open redirect.
(CVE-2017-7233)

Phithon Gong discovered that Django incorrectly handled certain URLs when the jango.views.static.serve() view is being used. A remote attacker could possibly use a Django server as an open redirect.
(CVE-2017-7234).

This update for python3-Django to version 1.18.18 fixes multiple issues. Security issues fixed :

  - CVE-2018-7537: Fixed catastrophic backtracking in     django.utils.text.Truncator. (bsc#1083305)

  - CVE-2018-7536: Fixed catastrophic backtracking in urlize     and urlizetrunc template filters (bsc#1083304).

  - CVE-2016-7401: CSRF protection bypass on a site with     Google Analytics (bsc#1001374).

  - CVE-2016-2513: User enumeration through timing     difference on password hasher work factor upgrade     (bsc#968000).

  - CVE-2016-2512: Fixed malicious redirect and possible XSS     attack via user-supplied redirect URLs containing basic     auth (bsc#967999).

  - CVE-2016-9013: User with hardcoded password created when     running tests on Oracle (bsc#1008050).

  - CVE-2016-9014: DNS rebinding vulnerability when     DEBUG=True (bsc#1008047).

  - CVE-2017-7234: Open redirect vulnerability in     django.views.static.serve() (bsc#1031451).

  - CVE-2017-7233: Open redirect and possible XSS attack via     user-supplied numeric redirect URLs (bsc#1031450).

  - CVE-2017-12794: Fixed XSS possibility in traceback     section of technical 500 debug page (bsc#1056284)

It was discovered that there were two vulnerabilities in python-django, a high-level Python web development framework.

CVE-2017-7233 (#859515): Open redirect and possible XSS attack via user-supplied numeric redirect URLs. Django relies on user input in some cases (e.g. django.contrib.auth.views.login() and i18n) to redirect the user to an 'on success' URL. The security check for these redirects (namely is_safe_url()) considered some numeric URLs (e.g.
http:999999999) 'safe' when they shouldn't be. Also, if a developer relied on is_safe_url() to provide safe redirect targets and puts such a URL into a link, they could suffer from an XSS attack.

CVE-2017-7234 (#895516): Open redirect vulnerability in django.views.static.serve; A maliciously crafted URL to a Django site using the serve() view could redirect to any other domain. The view no longer does any redirects as they don't provide any known, useful functionality.

For Debian 7 'Wheezy', this issue has been fixed in python-django version 1.4.22-1+deb7u3.

We recommend that you upgrade your python-django packages.

update to 1.9.13, fix for CVE-2017-7233

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several vulnerabilities were discovered in Django, a high-level Python web development framework. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2016-9013     Marti Raudsepp reported that a user with a hard-coded     password is created when running tests with an Oracle     database.

  - CVE-2016-9014     Aymeric Augustin discovered that Django does not     properly validate the Host header against     settings.ALLOWED_HOSTS when the debug setting is     enabled. A remote attacker can take advantage of this     flaw to perform DNS rebinding attacks.

  - CVE-2017-7233     It was discovered that is_safe_url() does not properly     handle certain numeric URLs as safe. A remote attacker     can take advantage of this flaw to perform XSS attacks     or to use a Django server as an open redirect.

  - CVE-2017-7234     Phithon from Chaitin Tech discovered an open redirect     vulnerability in the django.views.static.serve() view.
    Note that this view is not intended for production use.

This update for python-Django to version 1.18.18 fixes multiple issues. Security issues fixed :
