The session backends in Django before 1.4.21, 1.5.x through 1.6.x, 1.7.x before 1.7.9, and 1.8.x before 1.8.3 allows remote attackers to cause a denial of service (session store consumption) via multiple requests with unique session keys.

The remote host is affected by the vulnerability described in GLSA-201510-06 (Django: Multiple vulnerabilities)

    Multiple vulnerabilities have been found in Django:
      Session backends create a new record anytime request.session was         accessed (CVE-2015-5143)       Built-in validators in Django do not properly sanitize input         (CVE-2015-5144)       URL validation included a regular expression that was extremely slow         (CVE-2015-5145)   Impact :

    A remote attacker may be able cause a Denial of Service condition,       inject arbitrary headers, and conduct HTTP response splitting attacks.
  Workaround :

    There is no known workaround at this time.

python-django was updated to fix two security issues.

These security issues were fixed :

  - CVE-2015-5144: Django before 1.4.21, 1.5.x through     1.6.x, 1.7.x before 1.7.9, and 1.8.x before 1.8.3 used     an incorrect regular expression, which allowed remote     attackers to inject arbitrary headers and conduct HTTP     response splitting attacks via a newline character in an     (1) email message to the EmailValidator, a (2) URL to     the URLValidator, or unspecified vectors to the (3)     validate_ipv4_address or (4) validate_slug validator     (bsc#937523).

  - CVE-2015-5143: The session backends in Django before     1.4.21, 1.5.x through 1.6.x, 1.7.x before 1.7.9, and     1.8.x before 1.8.3 allowed remote attackers to cause a     denial of service (session store consumption) via     multiple requests with unique session keys (bsc#937522).

update to 1.8.3 fixing 3 CVE

Several vulnerabilities were discovered in Django, a high-level Python web development framework :

CVE-2015-2317

Daniel Chatfield discovered that python-django, a high-level Python web development framework, incorrectly handled user-supplied redirect URLs. A remote attacker could use this flaw to perform a cross-site scripting attack.

CVE-2015-5143

Eric Peterson and Lin Hua Cheng discovered that a new empty record used to be created in the session storage every time a session was accessed and an unknown session key was provided in the request cookie. This could allow remote attackers to saturate the session store or cause other users' session records to be evicted.

CVE-2015-5144

Sjoerd Job Postmus discovered that some built-in validators did not properly reject newlines in input values. This could allow remote attackers to inject headers in emails and HTTP responses.

For the oldoldstable distribution (squeeze), these problems have been fixed in version 1.2.3-3+squeeze13.

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2671-1 advisory.

    Eric Peterson and Lin Hua Cheng discovered that Django incorrectly handled session records. A remote     attacker could use this issue to cause a denial of service. (CVE-2015-5143)

    Sjoerd Job Postmus discovered that DJango incorrectly handled newline characters when performing     validation. A remote attacker could use this issue to perform header injection attacks. (CVE-2015-5144)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Tim Graham reports :

In accordance with our security release policy, the Django team is issuing multiple releases -- Django 1.4.21, 1.7.9, and 1.8.3. These releases are now available on PyPI and our download page. These releases address several security issues detailed below. We encourage all users of Django to upgrade as soon as possible. The Django master branch has also been updated.
