Descriptions

There is a DoS vulnerability in Pillow before 6.2.2 caused by FpxImagePlugin.py calling the range function on an unvalidated 32-bit integer if the number of bands is large. On Windows running 32-bit Python, this results in an OverflowError or MemoryError due to the 2 GB limit. However, on Linux running 64-bit Python this results in the process being terminated by the OOM killer.

Hay una vulnerabilidad DoS en Pillow versiones anteriores a la versión 6.2.2, causada por el archivo FpxImagePlugin.py llamando a la función range en un entero de 32 bits sin validar si el número de bandas es grande. En Windows ejecutando Python de 32 bits, esto resulta en un OverflowError o MemoryError debido al límite de 2 GB. Sin embargo, en Linux ejecutando Python de 64 bits, esto resulta en que el proceso sea terminado por el asesino OOM.

A denial of service vulnerability was found in Pillow in versions before 6.2.2, where the FpxImagePlugin.py file calls the range function on an unvalidated 32-bit integer if the number of bands is large. On Windows systems running 32-bit Python, this flaw results in an OverflowError or MemoryError due to the 2 GB limit. On Linux systems running 64-bit Python, this flaw results in the termination of the process by the out-of-memory (OOM) killer. The highest threat from this vulnerability is to system availability.
