How to Fix CVE-2022-41895

To remediate this vulnerability, upgrade all affected Tensorflow cpu dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

tensorflow-cpu fixed: 2.10.1 
pip install tensorflow-cpu>=2.10.1
tensorflow-gpu fixed: 2.10.1 
pip install tensorflow-gpu>=2.10.1
tensorflow fixed: 2.10.1 
pip install tensorflow>=2.10.1
tensorflow fixed: 2.8.4 
pip install tensorflow>=2.8.4
tensorflow fixed: 2.9.3 
pip install tensorflow>=2.9.3
tensorflow-cpu fixed: 2.8.4 
pip install tensorflow-cpu>=2.8.4
tensorflow-gpu fixed: 2.8.4 
pip install tensorflow-gpu>=2.8.4
tensorflow-cpu fixed: 2.9.3 
pip install tensorflow-cpu>=2.9.3
tensorflow-gpu fixed: 2.9.3 
pip install tensorflow-gpu>=2.9.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show tensorflow-cpu

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2022-41895, inspect your installed packages using pip:

pip show tensorflow-cpu

Analyze the terminal output to locate any version of Tensorflow cpu in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.10.1), your application is affected.

Note: The pip show tensorflow-cpu command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-125: Out-of-bounds Read, where the product reads data past the end, or before the beginning, of the intended buffer. In Tensorflow cpu, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact If [`MirrorPadGrad`](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/core/kernels/image/mirror_pad_op.cc) is given outsize input `paddings`, TensorFlow will give a heap OOB error. ```python import tensorflow as tf tf.raw_ops.MirrorPadGrad(input=[1], paddings=[[0x77f00000,0xa000000]], mode = 'REFLECT') ``` ### Patches We have patched the issue in GitHub commit [717ca98d8c3bba348ff62281fdf38dcb5ea1ec92](https://github.com/tensorflow/tensorflow/commit/717ca98d8c3bba348ff62281fdf38dcb5ea1ec92). The fix will be included in TensorFlow 2.11. We will also cherrypick this commit on TensorFlow 2.10.1, 2.9.3, and TensorFlow 2.8.4, as these are also affected and still in supported range. ### For more information Please consult [our security guide](https://github.com/tensorflow/tensorflow/blob/master/SECURITY.md) for more information regarding the security model and how to contact us with issues and questions. ### Attribution This vulnerability has been reported by Vul AI.
