Low
mihaimaruseac published GHSA-cwpm-f78v-7m5c May 17, 2022

Package

pip tensorflow, tensorflow-cpu, tensorflow-gpu (pip)

Affected versions

< 2.9.0

Patched versions

2.6.4, 2.7.2, 2.8.1, 2.9.0

Description

Impact

The implementation of tf.ragged.constant does not fully validate the input arguments. This results in a denial of service by consuming all available memory:

import tensorflow as tf
tf.ragged.constant(pylist=[],ragged_rank=8968073515812833920)

Patches

We have patched the issue in GitHub commit bd4d5583ff9c8df26d47a23e508208844297310e.

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.
