PYSEC-2021-605

TensorFlow is an end-to-end open source platform for machine learning. In affected versions under certain conditions, Go code can trigger a segfault in string deallocation. For string tensors, C.TFTStringDealloc is called during garbage collection within a finalizer function. However, tensor...

CVE-2021-37678 Arbitrary code execution due to YAML deserialization

TensorFlow is an end-to-end open source platform for machine learning. In affected versions TensorFlow and Keras can be tricked to perform arbitrary code execution when deserializing a Keras model from YAML format.

CVE-2021-37692 Segfault on strings tensors with mistmatched dimensions in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. In affected versions under certain conditions, Go code can trigger a segfault in string deallocation. For string tensors, C.TFTStringDealloc is called during garbage collection within a finalizer function. However, tensor...

CVE-2021-37692

CVE-2021-37692 affects TensorFlow and centers on a segfault in string tensor deallocation during garbage collection when the encoding of a string tensor fails (e.g., mismatched dimensions). The root cause is an assumption that encoding succeeded, leading to use of the finalizer of the tensor with...

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 Incomplete validation in `QuantizeV2` in TensorFlow

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-2021-37674 Incomplete validation in `MaxPoolGrad` in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can trigger a denial of service via a segmentation fault in tf.rawops.MaxPoolGrad caused by missing validation. The implementation misses some validation for the originput and origoutput tensor...

CVE-2021-37683

TensorFlow (TFLite division) vulnerability (CVE-2021-37683): In affected builds, division in TFLite can produce a division-by-zero error because there is no check that the divisor tensor contains zero. The issue was addressed in commit 1e206baedf8bef0334cca3eb92bab134ef525a28 and the fix is plann...

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