cached session data. A remote attacker could exploit this to modify
sessions. (CVE-2011-4136)

Paul McMillan discovered that Django would not timeout on arbitrary URLs
when the application used URLFields. This could be exploited by a remote
attacker to cause a denial of service via resource exhaustion.
(CVE-2011-4137)

Paul McMillan discovered that while Django would check the validity of a
URL via a HEAD request, it would instead use a GET request for the target
of a redirect. This could potentially be used to trigger arbitrary GET
requests via a crafted Location header. (CVE-2011-4138)

It was discovered that Django would sometimes use a request's HTTP Host
header to construct a full URL. A remote attacker could exploit this to
conduct host header cache poisoning attacks via a crafted request.
