Descriptions

In LibTIFF 4.0.8, there is a denial of service vulnerability in the TIFFOpen function. A crafted input will lead to a denial of service attack. 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 we set the value of td_imagelength close to the amount of system memory, it will hang the system or trigger the OOM killer.

En LibTIFF 4.0.8, existe una vulnerabilidad de denegación de servicio (DoS) en la función TIFFOpen. Se podría realizar un ataque de denegación de servicio con una entrada especialmente manipulada. Durante el proceso TIFFOpen, no se verifica td_imagelength. El valor de td_imagelength se puede controlar directamente por un archivo de entrada. En la función ChopUpSingleUncompressedStrip , se llama a la función _TIFFCheckMalloc en base a td_imagelength. Si se establece un valor para td_imagelenght cercano a la cantidad de memoria del sistema, el sistema se colgará o se activará el killer OOM.
