Upgrade tensorflow to version 2.4.0rc0 or higher.
Overview
tensorflow is a machine learning framework.
Affected versions of this package are vulnerable to Improper Input Validation. The tf.raw_ops.ImmutableConst operation returns a constant tensor created from a memory mapped file which is assumed immutable. However, if the type of the tensor is not an integral type, the operation crashes the Python interpreter as it tries to write to the memory area:
If the file is too small, TensorFlow properly returns an error as the memory area has fewer bytes than what is needed for the tensor it creates. However, as soon as there are enough bytes, the above snippet causes a segmentation fault.
