CVE-2022-29216 Information

Description

TensorFlow is an open source platform for machine learning. Prior to versions 2.9.0 2.8.1 2.7.2 and 2.6.4 TensorFlow’s saved_model_cli tool is vulnerable to a code injection. This can be used to open a reverse shell. This code path was maintained for compatibility reasons as the maintainers had several test cases where numpy expressions were used as arguments. However given that the tool is always run manually the impact of this is still not severe. The maintainers have now removed the safe=False argument so all parsing is done without calling eval. The patch is available in versions 2.9.0 2.8.1 2.7.2 and 2.6.4.
