Here is a patch for 3.3+.
Other versions are affected too. They don't raise SystemError, but produce illegal unicode string on wide build.
E.g. in Python 2.7:
>>> 'a+/,+IKw-b'.decode('utf-7', 'replace')
u'a\ufffd\U003f20acb'
\U003f20ac is illegal code.
As encoding and encoded data can come from external source, this can be used in secure attacks. |
