CVE-2022-21728

Tensorflow is an Open Source Machine Learning Framework. The implementation of shape inference for ReverseSequence does not fully validate the value of batchdim and can result in a heap OOB read. There is a check to make sure the value of batchdim does not go over the rank of the input, but there...

CVE-2022-21728

CVE-2022-21728 affects TensorFlow: ReverseSequence shape-inference can yield a heap-based out-of-bounds read because batch_dim is checked for being too large but not for negative values. The mitigation path is a forthcoming fix in TensorFlow 2.8.0, with cherry-picks into 2.7.1, 2.6.3, and 2.5.3. ...

Being Naughty to See Who Was Nice: Machine Learning Attacks on Santa’s List

Editor’s note: We had planned to publish our Hacky Holidays blog series throughout December 2021 – but then Log4Shell happened, and we dropped everything to focus on this major vulnerability that impacted the entire cybersecurity community worldwide. Now that it’s 2022, we’re feeling in need of...

Google TensorFlow Buffer Overflow Vulnerability (CNVD-2022-09870)

Google TensorFlow is a suite of end-to-end open source platforms for machine learning from Google USA. A buffer overflow vulnerability exists in Google TensorFlow, which stems from undefined behavior of the shape inference code of "tf.ragged.cross" due to a bound reference to "nullptr" in the...
