Descriptions
There's a flaw in OpenEXR's deep tile sample size calculations in versions before 3.0.0-beta. An attacker who is able to submit a crafted file to be processed by OpenEXR could trigger an integer overflow, subsequently leading to an out-of-bounds read. The greatest risk of this flaw is to application availability.
Se presenta un fallo en los cálculos de tamaño de la muestra de mosaicos profundos de OpenEXR versiones anteriores a la 3.0.0-beta. Un atacante que pueda ser capaz de enviar un archivo diseñado para que sea procesado por OpenEXR podría desencadenar un desbordamiento de enteros, posteriormente conllevando a una lectura fuera de límites. El mayor riesgo de este fallo es la disponibilidad de la aplicación.
