_TIFFCheckMalloc and _TIFFCheckRealloc in tif_aux.c in LibTIFF through 4.0.10 mishandle Integer Overflow checks because they rely on compiler behavior that is undefined by the applicable C standards. This can, for example, lead to an application crash. tif_getimage.c in LibTIFF through 4.0.10, as used in GDAL through 3.0.1 and other products, has an integer overflow that potentially causes a heap-based buffer overflow via a crafted RGBA image, related to a "Negative-size-param" condition
