Safety vulnerability ID: 44867
The information on this page was manually curated by our Cybersecurity Intelligence Team.
Tensorflow versions 2.5.3, 2.6.3, 2.7.1 and 2.8.0 include a fix for CVE-2022-23582: A malicious user can cause a denial of service by altering a 'SavedModel' such that 'TensorByteSize' would trigger 'CHECK' failures. 'TensorShape' constructor throws a 'CHECK'-fail if shape is partial or has a number of elements that would overflow the size of an 'int'. The 'PartialTensorShape' constructor instead does not cause a 'CHECK'-abort if the shape is partial, which is exactly what this function needs to be able to return '-1'.

TensorFlow is an open source machine learning framework for everyone.
Tensorflow is an Open Source Machine Learning Framework. A malicious user can cause a denial of service by altering a `SavedModel` such that `TensorByteSize` would trigger `CHECK` failures. `TensorShape` constructor throws a `CHECK`-fail if shape is partial or has a number of elements that would overflow the size of an `int`. The `PartialTensorShape` constructor instead does not cause a `CHECK`-abort if the shape is partial, which is exactly what this function needs to be able to return `-1`. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range. See CVE-2022-23582.
