Name of the Vulnerable Software and Affected Versions TensorFlow versions prior to 2.9.0 TensorFlow versions prior to 2.8.1 TensorFlow versions prior to 2.7.2 TensorFlow versions prior to 2.6.4

Description The implementation of tf.raw ops.GetSessionTensor does not fully validate the input arguments, resulting in a CHECK-failure that can be used to trigger a denial of service attack. This issue can be exploited by passing invalid input to the tf.raw ops.GetSessionTensor function, which assumes the handle is a scalar but lacks validation for this.

Recommendations For versions prior to 2.9.0, update to version 2.9.0 or later. For versions prior to 2.8.1, update to version 2.8.1 or later. For versions prior to 2.7.2, update to version 2.7.2 or later. For versions prior to 2.6.4, update to version 2.6.4 or later.
