CWE-125  (opens in a new tab)

How to fix?

Upgrade tensorflow-cpu to version 2.7.0, 2.6.1, 2.5.2, 2.4.4 or higher.

Overview

tensorflow-cpu is a machine learning framework.

Affected versions of this package are vulnerable to Out-of-bounds Read via the ImmutableConst operation which can be tricked into reading arbitrary memory contents. This is because the tstring TensorFlow string class has a special case for memory mapped strings but the operation itself does not offer any support for this datatype.
