Descriptions

An issue was discovered in Pillow before 8.2.0. PSDImagePlugin.PsdImageFile lacked a sanity check on the number of input layers relative to the size of the data block. This could lead to a DoS on Image.open prior to Image.load.

Se ha detectado un problema en Pillow versiones anteriores a 8.2.0, PSDImagePlugin.PsdImageFile carecía de una comprobación de saneamiento sobre el número de capas de entrada en relación con el tamaño del bloque de datos. Esto podría conllevar a un DoS en Image.open anterior a Image.load

A flaw was found in python-pillow. PsdImagePlugin.PsdImageFile does not sanity check the number of input layers with regard to the size of the data block which could lead to a denial-of-service.
