Descriptions

Integer overflow in libaom internal function img_alloc_helper can lead to heap buffer overflow. This function can be reached via 3 callers:


* Calling aom_img_alloc() with a large value of the d_w, d_h, or align parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned aom_image_t struct may be invalid.
* Calling aom_img_wrap() with a large value of the d_w, d_h, or align parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned aom_image_t struct may be invalid.
* Calling aom_img_alloc_with_border() with a large value of the d_w, d_h, align, size_align, or border parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned aom_image_t struct may be invalid.

El desbordamiento de enteros en la función interna de libaom img_alloc_helper puede provocar un desbordamiento del búfer del montón. Se puede acceder a esta función a través de 3 llamadores: * Llamar a aom_img_alloc() con un valor grande del parámetro d_w, d_h o align puede resultar en desbordamientos de enteros en los cálculos de tamaños y compensaciones del búfer y algunos campos de la estructura aom_image_t devuelta pueden ser inválido. * Llamar a aom_img_wrap() con un valor grande del parámetro d_w, d_h o align puede provocar desbordamientos de enteros en los cálculos de tamaños y compensaciones del búfer y algunos campos de la estructura aom_image_t devuelta pueden no ser válidos. * Llamar a aom_img_alloc_with_border() con un valor grande del parámetro d_w, d_h, align, size_align o border puede provocar desbordamientos de enteros en los cálculos de tamaños y compensaciones del búfer y algunos campos de la estructura aom_image_t devuelta pueden no ser válidos.
