Descriptions
In libpng 1.6.34, a wrong calculation of row_factor in the png_check_chunk_length function (pngrutil.c) may trigger an integer overflow and resultant divide-by-zero while processing a crafted PNG file, leading to a denial of service.
En libpng 1.6.34, un cálculo erróneo de row_factor en la función png_check_chunk_length (pngrutil.c) podría desencadenar un desbordamiento de enteros y una división entre cero resultante al procesar un archivo PNG manipulado, lo que conduciría a una denegación de servicio (DoS).
