Missing validation causes denial of service via `StagePeek`
Impact
The implementation of tf.raw_ops.StagePeek does not fully validate the input arguments. This results in a CHECK-failure which can be used to trigger a denial of service attack:
import tensorflow as tf
index = tf.constant([], shape=[0], dtype=tf.int32)
tf.raw_ops.StagePeek(index=index, dtypes=[tf.int32])The code assumes index is a scalar but there is no validation for this before accessing its value:
std::size_t index = ctx->input(0).scalar<int>()();Patches
We have patched the issue in GitHub commit cebe3c45d76357d201c65bdbbf0dbe6e8a63bbdb.
The fix will be included in TensorFlow 2.9.0. We will also cherrypick this commit on TensorFlow 2.8.1, TensorFlow 2.7.2, and TensorFlow 2.6.4, as these are also affected and still in supported range.
