malloc without NULL check

[andreas moroder]

Hello,

in rastertolabel.c the return values of malloc are never checked for NULL value.

in rastertoescpx.c line 1004 no NULL check
      band         = (cups_weave_t *)calloc(1, sizeof(cups_weave_t));
      band->next   = DotAvailList;

   line 1031

      PixelBuffer      = malloc(header->cupsBytesPerLine);
      InputBuffer      = malloc(header->cupsWidth * PrinterPlanes * 2);
      OutputBuffers[0] = malloc(PrinterPlanes * header->cupsWidth);

  for (i = 1; i < PrinterPlanes; i ++)
    OutputBuffers[i] = OutputBuffers[0] + i * header->cupsWidth;


in rastertopclx.c line 771 no NULL check and all the following mallocs


in snmp.c at line 313 no NULL check
  temp = calloc(1, sizeof(snmp_cache_t));
  memcpy(&(temp->address), addr, sizeof(temp->address));

and more in other places in cups-1.4svn-r7613

Bye
Andreas
