 Hi libTiff community,

libTiff library crashes for a particular large chunky tiled YCbCr image when using the RGBA interface.

I tried this with your latest libTiff version (4.0.9) and earlier versions as well.

#include <tiffio.h>

int main()
{
    TIFF *tif=TIFFOpen("Test_001.tif", "r");
    uint32 width;
    uint32 height;
    TIFFGetField(tif, TIFFTAG_IMAGEWIDTH, &width);
    TIFFGetField(tif, TIFFTAG_IMAGELENGTH, &height);

    uint32 npixels=width*height;

    uint32* raster=(uint32 *) _TIFFmalloc(npixels *sizeof(uint32));
    TIFFReadRGBAImage(tif, width, height, raster, 0);

}

Please let me know if this can be fixed and in which release it will be fixed?

Thanks,
