How to fix?

Upgrade tensorflow to version 2.5.1, 2.4.3 or higher.

Overview

tensorflow is a machine learning framework.

Affected versions of this package are vulnerable to Integer Overflow. The implementation of tf.raw_ops.QuantizeAndDequantizeV4Grad is vulnerable to an integer overflow issue caused by converting a signed integer value to an unsigned one and then allocating memory based on this value. The implementation uses the axis value as the size argument to absl::InlinedVector constructor. But, the constructor uses an unsigned type for the argument, so the implicit conversion transforms the negative value to a large integer.
