CVE-2022-35997

Name of the Vulnerable Software and Affected Versions TensorFlow versions prior to 2.10.0 TensorFlow versions 2.9.1 and earlier TensorFlow versions 2.8.1 and earlier TensorFlow versions 2.7.2 and earlier

Description The issue occurs when the tf.sparse.cross function receives an input separator that is not a scalar, resulting in a CHECK fail that can be used to trigger a denial of service attack. This can happen when the separator input is not properly validated, allowing an attacker to cause the program to crash or become unresponsive.

Recommendations For versions prior to 2.10.0, update to TensorFlow 2.10.0 or later to resolve the issue. For versions 2.9.1 and earlier, update to TensorFlow 2.9.1 or later to resolve the issue. For versions 2.8.1 and earlier, update to TensorFlow 2.8.1 or later to resolve the issue. For versions 2.7.2 and earlier, update to TensorFlow 2.7.2 or later to resolve the issue. As a temporary workaround, consider validating the separator input to ensure it is a scalar before passing it to the tf.sparse.cross function.
