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.UnsortedSegmentJoin 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 assumes num segments is a positive scalar but there is no validation. Since this value is used to allocate the output tensor, a negative value would result in a CHECK-failure.

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 validating the num segments value before passing it to tf.raw ops.UnsortedSegmentJoin to prevent negative values.
