CVE-2021-29519: Access of Resource Using Incompatible Type (Type Confusion)
(updated )
TensorFlow is an end-to-end open source platform for machine learning. The API of tf.raw_ops.SparseCross
allows combinations which would result in a CHECK
-failure and denial of service. This is because the implementation is tricked to consider a tensor of type tstring
which in fact contains integral elements. Fixing the type confusion by preventing mixing DT_STRING
and DT_INT64
types solves this issue.
