Segfault due to negative splits in `SplitV` ### Impact The implementation https://github.com/tensorflow/tensorflow/blob/e71b86d47f8bc1816bf54d7bddc4170e47670b97/tensorflow/core/kernels/split_v_op.cc#L49-L205 of `SplitV` can trigger a segfault is an attacker supplies negative arguments: ```python import tensorflow as tf tf.raw_ops.SplitV( value=tf.constant([]), size_splits=[-1, -2] ,axis=0, num_split=2) ``` This occurs whenever `size_splits` contains more than one value and at least one value is negative. ### Patches We have patched the issue in GitHub commit 25d622ffc432acc736b14ca3904177579e733cc6 https://github.com/tensorflow/tensorflow/commit/25d622ffc432acc736b14ca3904177579e733cc6. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range. ### For more information Please consult our security guide https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md for more information regarding the security model and how to contact us with issues and questions. ### Attribution This vulnerability has been reported by members of the Aivul Team from Qihoo 360.

TensorFlow is an open source platform for machine learning. In affected versions the implementation of `SplitV` can trigger a segfault is an attacker supplies negative arguments. This occurs whenever `size_splits` contains more than one value and at least one value is negative. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range.
