CVE-2020-26266  (opens in a new tab)
CWE-908  (opens in a new tab)

How to fix?

Upgrade tensorflow/tensorflow to version 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2 or higher.

Overview

Affected versions of this package are vulnerable to Use of Uninitialized Resource. In affected versions of TensorFlow under certain cases a saved model can trigger use of uninitialized values during code execution. This is caused by having tensor buffers be filled with the default value of the type but forgetting to default initialize the quantized floating point types in Eigen. This is fixed in versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and 2.4.0.
