CWE-476  (opens in a new tab)

How to fix?

Upgrade tensorflow-cpu to version 2.3.4, 2.4.3, 2.5.1 or higher.

Overview

tensorflow-cpu is a machine learning framework.

Affected versions of this package are vulnerable to NULL Pointer Dereference. An attacker can craft a TFLite model that would trigger a null pointer dereference, which would result in a crash and denial of service. This is caused by the MLIR optimization of L2NormalizeReduceAxis operator. The implementation unconditionally dereferences a pointer to an iterator to a vector without checking that the vector has elements.
