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 Use of Uninitialized Variable. During execution, EinsumHelper::ParseEquation() is supposed to set the flags in input_has_ellipsis vector and *output_has_ellipsis boolean to indicate whether there is ellipsis in the corresponding inputs and output. The code only changes these flags to true and never assigns false. This results in unitialized variable access if callers assume that EinsumHelper::ParseEquation() always sets these flags.
