<pre>There is a similar bug at CairoOutputDev.cc:2598:
2596 for (y = 0; y < height; y++) {
2597 dest = (unsigned int *) (buffer + y * row_stride);
2598 pix = imgStr->getLine();
2599 colorMap->getRGBLine (pix, dest, width);
2600 }
The returned value for getLine is not validated. And in some scenarios this
value is NULL, so a NULL pointer dereference happens and poppler crashes.</pre>
