CVE-2022-29204 Information

Jun 07, 2022 cve

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 the implementation of tf.raw_ops.UnsortedSegmentJoin does not fully validate the input arguments. This results in a CHECK-failure which can be used to trigger a denial of service attack. The code assumes num_segments is a positive scalar but there is no validation. Since this value is used to allocate the output tensor a negative value would result in a CHECK-failure (assertion failure) as per TFSA-2021-198. Versions 2.9.0 2.8.1 2.7.2 and 2.6.4 contain a patch for this issue.
