CVE-2022-23588: `CHECK`-fails due to attempting to build a reference tensor in Tensorflow

Published Feb 4, 2022
·
Updated

Impact A malicious user can cause a denial of service by altering a SavedModel such that Grappler optimizer would attempt to build a tensor using a reference dtype. This would result in a crash due to a CHECK-fail in the Tensor constructor as reference types are not allowed. Patches We have patched the issue in GitHub commit 6b5adc0877de832b2a7c189532dbbbc64622eeb6. 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.
