Python: Fix for CVE-2012-2135
Reference:http://http://bugs.python.org/issue14579
The utf-16 decoder in Python 3.1 through 3.3 does not update the
aligned_end variable after calling the unicode_decode_call_errorhandler
function, which allows remote attackers to obtain sensitive information
(process memory) or cause a denial of service (memory corruption and crash)
via unspecified vectors.
