You'll need to contact iDefense for the numbers, we don't have them.

There is a simple patch for ReadBlobString() of magick/blob.c.  Change

  for (i=0; i < MaxTextExtent; i++)

to

  for (i=0; i < (MaxTextExtent-1L); i++)

The integer overflow problem was fixed by changing virtually all calls to
AcquireMagickMemory() and ResizeMagickMemory() to AcquireQuantumMemory()
and ResizeQuantumMemory() respectively:

MagickExport void *AcquireQuantumMemory(const size_t count,const size_t quantum)
{
  size_t
    size;

  size=count*quantum;
  if ((count == 0) || (quantum != (size/count)))
    {
      errno=ENOMEM;
      return((void *) NULL);
    }
  return(AcquireMagickMemory(size));
}

MagickExport void *ResizeQuantumMemory(void *memory,const size_t count,
  const size_t quantum)
{
  size_t
    size;

  size=count*quantum;
  if ((count == 0) || (quantum != (size/count)))
    {
      errno=ENOMEM;
      return((void *) NULL);
    }
  return(ResizeMagickMemory(memory,size));
}
