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.LSTMBlockCell does not fully validate the input arguments, resulting in a CHECK-failure that can be used to trigger a denial of service attack. The code does not validate the ranks of any of the arguments to this API call, leading to CHECK-failures when the elements of the tensor are accessed.

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. As a temporary workaround, consider disabling the tf.raw ops.LSTMBlockCell function until a patch is available.
