Description

Stephen Stewart, Michael Nelson, Natalia Bidart and James Westby discovered that Django improperly removed Vary and Cache-Control headers from HTTP responses when replying to a request from an Internet Explorer or Chrome Frame client. An attacker may use this to retrieve private data or poison caches. This update removes workarounds for bugs in Internet Explorer 6 and 7. (CVE-2014-1418)

Peter Kuma and Gavin Wahl discovered that Django did not correctly validate some malformed URLs, which are accepted by some browsers. An attacker may use this to cause unexpected redirects. An update has been provided for 12.04 LTS, 12.10, 13.10, and 14.04 LTS; this issue remains unfixed for 10.04 LTS as no 'is_safe_url()' functionality existed in this version.

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