CVE-2021-28678

An issue was discovered in Pillow before 8.2.0. For BLP data, BlpImagePlugin did not properly check that reads (after jumping to file offsets) returned data. This could lead to a DoS where the decoder could be run a large number of times on empty data.

Se ha detectado un problema en Pillow versiones anteriores a 8.2.0,. En el caso de los datos BLP, la función BlpImagePlugin no comprobaba apropiadamente que las lecturas (después de saltar a los offsets de los archivos) devolvían datos. Esto podía conllevar a un DoS en el que el decodificador podía ser ejecutado un gran número de veces con datos vacíos
