[PATCH 0/2] KEYS: Fixes [ver #3]

[David Howells]

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:
