TensorFlow is an open source platform for machine learning. When tf.quantization.fake_quant_with_min_max_vars_gradient
receives input min
or max
that is nonscalar, it gives a CHECK
fail that can trigger a denial of service attack. We have patched the issue in GitHub commit f3cf67ac5705f4f04721d15e485e192bb319feed. The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range. There are no known workarounds for this issue.
