In affected versions the shape inference code for tf.rawops.Dequantize has a vulnerability that could trigger a denial of service via a segfault if an attacker provides invalid arguments. The shape inference implementation use...

PYSEC-2021-576

TensorFlow is an end-to-end open source platform for machine learning. In affected versions due to incomplete validation in tf.rawops.QuantizeV2, an attacker can trigger undefined behavior via binding a reference to a null pointer or can access data outside the bounds of heap allocated arrays. Th...

CVE-2021-37690

TensorFlow is an end-to-end open source platform for machine learning. In affected versions when running shape functions, some functions such as MutableHashTableShape produce extra output information in the form of a ShapeAndType struct. The shapes embedded in this struct are owned by an inferenc...

CVE-2021-37669 Crash in NMS ops caused by integer conversion to unsigned in TensorFlow

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.NonMaxSuppressionV5 by triggering a division by 0. The implementation uses a user controlled argument to resize a...

CVE-2021-37663

CVE-2021-37663 arises from incomplete validation in tf.raw_ops.QuantizeV2 in TensorFlow. Affected: TensorFlow versions before 2.6.0 (patch committed 6da6620...). The issue can trigger undefined behavior via binding a null pointer or out-of-bounds access; if axis is provided, min_range/max_range l...

CVE-2021-37665

CVE-2021-37665 : TensorFlow vulnerable due to incomplete validation in MKL requantization (range per-channel and per-channel ops). The root cause is insufficient validation of input dimensions/arguments, allowing undefined behavior (binding a null pointer, heap out-of-bounds access). A patch was ...

CVE-2021-37684 Division by zero in TensorFlow Lite pooling operations

TensorFlow is an end-to-end open source platform for machine learning. In affected versions the implementations of pooling in TFLite are vulnerable to division by 0 errors as there are no checks for divisors not being 0. We have patched the issue in GitHub commit...

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-2021-37670 Heap OOB in `UpperBound` and `LowerBound` 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.UpperBound. The implementation does not validate the rank of sortedinput...

CVE-2021-37691

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 division by zero error in LSH implementation. We have patched the issue in GitHub commit 0575b640091680cfb70f4dd93e70658de43b94f9. The fix will be...

CVE-2021-37691 Division by zero in LSH in TensorFlow Lite

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...
