Name of the Vulnerable Software and Affected Versions TensorFlow versions prior to 2.11 TensorFlow version 2.10.1 TensorFlow version 2.9.3 TensorFlow version 2.8.4

Description TensorFlow is an open source platform for machine learning. An input token that is not a UTF-8 bytestring will trigger a CHECK fail in tf.raw ops.PyFunc.

Recommendations For TensorFlow versions prior to 2.11, update to version 2.11 or later. For TensorFlow version 2.10.1, apply the patch from GitHub commit 9f03a9d3bafe902c1e6beb105b2f24172f238645. For TensorFlow version 2.9.3, apply the patch from GitHub commit 9f03a9d3bafe902c1e6beb105b2f24172f238645. For TensorFlow version 2.8.4, apply the patch from GitHub commit 9f03a9d3bafe902c1e6beb105b2f24172f238645. As a temporary workaround, consider validating the input token to ensure it is a UTF-8 bytestring before passing it to tf.raw ops.PyFunc.
