During the TIFFOpen process, td_imagelength is not checked. The value of td_imagelength can be directly controlled by an input file. In the ChopUpSingleUncompressedStrip function, the _TIFFCheckMalloc function is called based on td_imagelength. If the value of td_imagelength is set close to the amount of system memory, it will hang the system or trigger the OOM killer (bsc#1082332). - CVE-2018-8905: Prevent heap-based buffer overflow in the function LZWDecodeCompat via a crafted TIFF file (bsc#1086408).
