Description Jan Lieskovsky 2012-04-25 07:10:31 EDT
A security flaw was found in the way the UTF-16 decoder of Python, an interpreted, interactive, object-oriented programming language, handled error messages after processing of certain UTF-16 strings. If a Python UTF-16 module based application provided remote means to accept unsanitized input, a remote attacker could use this flaw to cause denial of service (python executable to leak data, cause memory damage and possibly crash).
