CVE-2021-29516: NULL Pointer Dereference
TensorFlow is an end-to-end open source platform for machine learning. Calling tf.raw_ops.RaggedTensorToVariant
with arguments specifying an invalid ragged tensor results in a null pointer dereference. The implementation of RaggedTensorToVariant
operations does not validate that the ragged tensor argument is non-empty. Since batched_ragged
contains no elements, batched_ragged.splits
is a null vector, thus batched_ragged.splits
will result in dereferencing nullptr
. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.
