Basically if you unpickle a string that came from an untrusted source
(say, a browser cookie from the Cookie module), the string can make
pickle load arbitrary modules and call arbitrary object constructors
in your application. The docs for the cookie module mention this and
there's an bug open on sourceforge to fix the pickle docs.
