Descriptions

The tjLoadImage function in libjpeg-turbo 2.0.1 has an integer overflow with a resultant heap-based buffer overflow via a BMP image because multiplication of pitch and height is mishandled, as demonstrated by tjbench.

La función tjLoadImage en libjpeg-turbo en 2.0.1 tiene un desbordamiento de enteros con un desbordamiento de búfer basado en memoria dinámica (heap) resultante mediante una imagen BMP. Esto se debe a que se gestiona de manera incorrecta la multiplicación del pitch y la altura, tal y como queda demostrado con tjbench.
