DESCRIPTION:
Some vulnerabilities have been reported in Django, which can be
exploited by malicious people to bypass certain security restrictions
and conduct script insertion and cross-site request forgery attacks.

1) The cross-site request forgery protection does not properly verify
requests with certain "X-Requested-With" headers, which can be
exploited to conduct cross-site request forgery attacks by using
certain browser plugins and HTTP redirects to send cross-domain HTTP
requests with spoofed headers.

2) Input passed via the filename of uploaded files is not properly
sanitised within the file field before being used. This can be
exploited to insert HTML and script code, which will executed in a
user's browser session in context of an affected site if malicious
data is viewed.

Successful exploitation requires that a file-storage backend that
does not properly sanitise the file name is used (no default
file-storage backends are affected).

3) The file-based session storage system does not properly sanitise
the key submitted in the session cookie, which can be exploited to
conduct directory traversal attacks.

Note: This only affects deployments on systems using path separators
other than specified in Python's "os.path.sep" (e.g. Windows
systems).

SOLUTION:
Update to version 1.1.4 or 1.2.5 or apply patches.
