Simon Butcher 334a87be0b Corrected URL/reference to MPI library 2015-10-14 22:56:44 +01:00
Manuel Pégourié-Gonnard 2d7083435d Fix references to non-standard SIZE_T_MAX 
Turns out C99 doesn't define SIZE_T_MAX, so let's not use it.

Manuel Pégourié-Gonnard 58fb49531d Fix potential buffer overflow in mpi_read_string() 
Found by Guido Vranken.

Two possible integer overflows (during << 2 or addition in BITS_TO_LIMB())
could result in far too few memory to be allocated, then overflowing the
buffer in the subsequent for loop.

Both integer overflows happen when slen is close to or greater than
SIZE_T_MAX >> 2 (ie 2^30 on a 32 bit system).

Note: one could also avoid those overflows by changing BITS_TO_LIMB(s << 2) to
CHARS_TO_LIMB(s >> 1) but the solution implemented looks more robust with
respect to future code changes.
