CVE-2021-37668 Division by zero in TensorFlow Lite `tf.raw_ops.UnravelIndex`

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can cause denial of service in applications serving models using tf.rawops.UnravelIndex by triggering a division by 0. The implementation does not check that the tensor subsumed by dims is not...

CVE-2021-37668

CVE-2021-37668 affects TensorFlow, specifically the tf.raw_ops.UnravelIndex path. The vulnerability arises when dims is empty and an element of dims is 0, leading to an division-by-zero in the implementation and enabling a denial-of-service in model-serving applications. The issue was patched in ...

CVE-2021-37670

TensorFlow vulnerability CVE-2021-37670 involves a heap-based out-of-bounds read in tf.raw_ops.UpperBound (and LowerBound) caused by missing rank validation of the sorted_input argument. A patch was committed (commit 42459e4273c2e47a3232cc16c4f4fff3b3a35c38) and the fix is slated for TensorFlow 2...

CVE-2021-37691

CVE-2021-37691 affects TensorFlow (Lite) where a crafted TFLite model can trigger a division-by-zero error in the LSH projection implementation. The issue is mitigated by a patch in the GitHub commit 0575b640091680cfb70f4dd93e70658de43b94f9, with the fix slated for inclusion in TensorFlow 2.6.0 a...

CVE-2021-37679

TensorFlow CVE-2021-37679 concerns a vulnerability in nested tf.map_fn with RaggedTensor inputs. The root cause is in the conversion from a Variant tensor to a RaggedTensor: the implementation does not verify that all inner shapes match, which can produce extra dimensions and allow leakage of hea...

CVE-2021-37672 Heap OOB in `SdcaOptimizerV2` in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can read from outside of bounds of heap allocated data by sending specially crafted illegal arguments to tf.rawops.SdcaOptimizerV2. The implementation does not check that the length of...

CVE-2021-37672

TensorFlow CVE-2021-37672 is a heap-based out-of-bounds read vulnerability in SdcaOptimizerV2 caused by not validating example_labels length against the number of examples. The issue is disclosed in GHSA-5HJ3-VJJF-F5M7 with a code example and fix details. Patches were applied in the GitHub commit...

CVE-2021-37687

CVE-2021-37687 describes a heap-based out-of-bounds read in TensorFlow Lite’s GatherNd and Gather, caused by missing index checks for negative values in indices. An attacker could read arbitrary heap data via crafted models. Patched in GitHub commits bb6a0383ed... and eb92112211..., with the fix ...

CVE-2021-37688

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can craft a TFLite model that would trigger a null pointer dereference, which would result in a crash and denial of service. The implementation unconditionally dereferences a pointer. We have...

CVE-2021-37652

TensorFlow is an end-to-end open source platform for machine learning. In affected versions the implementation for tf.rawops.BoostedTreesCreateEnsemble can result in a use after free error if an attacker supplies specially crafted arguments.
