Python3.4 / CVE-2016-5636



Supposedly this should be the patch for the problem:

https://hg.python.org/cpython/rev/fa006d671f41

However all I seem to be able to find is an empty patch. Although the
files listed is correct.

Can anyone here see how to find the correct patch?

There is a good patch here:

https://hg.python.org/cpython/rev/01ddd608b85c

However I think this is an earlier version that was criticised as being
insufficient:

https://bugs.python.org/issue26171#msg258779

The patch does sanitize the data_size value, however it looks like it
might be insufficient - as it catch negative values - not sure I really
understand just yet however - the description doesn't make 100% sense
and suggests that any small value of data_size might be a problem, not
just negative values.
