How to fix?

Upgrade tensorflow to version 2.6.1, 2.5.2, 2.4.4 or higher.

Overview

tensorflow is a machine learning framework.

Affected versions of this package are vulnerable to Buffer Overflow. When calculating the size of the output within the tf.range kernel, there is a conditional statement of type int64 = condition ? int64 : double. Due to C++ implicit conversion rules, both branches of the condition will be cast to double and the result would be truncated before the assignment.
