Weakness: CWE-20

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.Conv3DBackpropFilterV2` 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 does not validate that the `filter_sizes` argument is a vector. Versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4 contain a patch for this issue.

Affected products

tensorflow: before 2.6.4; from 2.7.0 before 2.7.2; 2.7.0-rc0, 2.7.0-rc1, 2.8.0, 2.8.0-rc0, 2.8.0-rc1, 2.9.0-rc0 (+1) — fixed in 2.6.4, 2.7.2

How to fix

Upgrade to a fixed version: tensorflow 2.6.4, 2.7.2. Check the vendor advisory for mitigations.
