#509 Memory leak in tiff.c

[BlueKiller]

Here is the critical code:

…
          blue=MagickAllocateMemory(unsigned short *,                //5205
                                    65536L*sizeof(unsigned short));
          green=MagickAllocateMemory(unsigned short *,
                                     65536L*sizeof(unsigned short));
          red=MagickAllocateMemory(unsigned short *,
                                   65536L*sizeof(unsigned short));
          if ((blue == (unsigned short *) NULL) ||
              (green == (unsigned short *) NULL) ||
              (red == (unsigned short *) NULL))
            ThrowWriterException(ResourceLimitError,MemoryAllocationFailed,    //5214
                                 image);
…

If one of the “blue”、“green” and “red" is not null in “if statement”,it may cause memory leak error.
