Summary:

Several security issues were fixed in Django.

Software Description:
- python-django: High-level Python web development framework

Details:

Andrey Babak discovered that Django incorrectly handled strip_tags. A
remote attacker could possibly use this issue to cause Django to enter an
infinite loop, resulting in a denial of service. This issue only affected
Ubuntu 14.04 LTS and Ubuntu 14.10. (CVE-2015-2316)

Daniel Chatfield discovered that Django incorrectly handled user-supplied
redirect URLs. A remote attacker could possibly use this issue to perform a
cross-site scripting attack. (CVE-2015-2317)

package versions:

Ubuntu 14.10:
  python-django                   1.6.6-1ubuntu2.2
