Hi James,
Can you pull these patches please and pass them on to Linus? They include the following:
(1) Fix mpi_powm()'s handling of a number with a zero exponent [CVE-2016-8650].
(2) Fix double free in X.509 error handling.
Ver #3:
- Integrate my and Andrey's patches for mpi_powm() and use mpi_resize() instead of RESIZE_IF_NEEDED() - the latter adds a duplicate check into the execution path of a trivial case we don't normally expect to be taken.
Ver #2:
- Use RESIZE_IF_NEEDED() to conditionally resize the result rather than manually doing this.
The patches can be found here also:
