CVE-2022-29205 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 there is a potential for segfault / denial of service in TensorFlow by calling tf.compat.v1. ops which don’t yet have support for quantized types which was added after migration to TensorFlow 2.x. In these scenarios since the kernel is missing a nullptr value is passed to ParseDimensionValue for the py_value argument. Then this is dereferenced resulting in segfault. Versions 2.9.0 2.8.1 2.7.2 and 2.6.4 contain a patch for this issue.
