python-django-piston - deserialization vulnerability

It was discovered that the Piston framework can deserializes untrusted
YAML and Pickle data, leading to remote code execution (CVE-2011-4103).

The old stable distribution (lenny) does not contain a
python-django-piston package.

For the stable distribution (squeeze), this problem has been fixed in
version 0.2.2-1+squeeze1.

For the testing distribution (wheezy) and the unstable distribution
(sid), this problem has been fixed in version 0.2.2-2.

We recommend that you upgrade your python-django-piston packages.
