CVE-2021-29532

Summary: CVE-2021-29532 affects TensorFlow and describes a heap out-of-bounds read in RaggedCross when processing tensors, due to missing validation of user-supplied indices in ragged/dense/sparse paths. The vulnerability arises from code that uses list indices (e.g., next_ragged/next_sparse/next...

CVE-2021-29535

CVE-2021-29535 affects TensorFlow’s QuantizedMul implementation. The vulnerability arises when four quantization thresholds are passed as inputs and may be empty tensors, causing a heap buffer overflow by accessing .flat()(0) on an empty buffer. This is rooted in the code path in quantized_mul_op...

CVE-2021-29538

TensorFlow CVE-2021-29538 concerns a division-by-zero in Conv2DBackpropFilter. The issue arises when shapes are empty, causing work_unit_size to be 0 and a divide operation to throw a runtime error, enabling potential denial-of-service conditions. Concrete details in connected docs specify the af...

CVE-2021-29539

TensorFlow is an end-to-end open source platform for machine learning. Calling tf.rawops.ImmutableConsthttps://www.tensorflow.org/apidocs/python/tf/rawops/ImmutableConst with a dtype of tf.resource or tf.variant results in a segfault in the implementation as code assumes that the tensor contents...

CVE-2021-29541 Null pointer dereference in `StringNGrams`

TensorFlow is an end-to-end open source platform for machine learning. An attacker can trigger a dereference of a null pointer in tf.rawops.StringNGrams. This is because the...

CVE-2021-29544 CHECK-fail in `QuantizeAndDequantizeV4Grad`

TensorFlow is an end-to-end open source platform for machine learning. An attacker can trigger a denial of service via a CHECK-fail in tf.rawops.QuantizeAndDequantizeV4Grad. This is because the implementation does not validate the rank of the input tensors. In turn, this results in the tensors...

CVE-2021-29546 Division by 0 in `QuantizedBiasAdd`

TensorFlow is an end-to-end open source platform for machine learning. An attacker can trigger an integer division by zero undefined behavior in tf.rawops.QuantizedBiasAdd. This is because the implementation of the Eigen...

CVE-2021-29548 Division by 0 in `QuantizedBatchNormWithGlobalNormalization`

TensorFlow is an end-to-end open source platform for machine learning. An attacker can cause a runtime division by zero error and denial of service in tf.rawops.QuantizedBatchNormWithGlobalNormalization. This is because the...

CVE-2021-29554

CVE-2021-29554 affects TensorFlow: DenseCountSparseOutput can cause a denial of service via a division-by-zero runtime error. Root cause is computing a divisor from user data without validating zero, yielding num_batch_elements = 0 and a divide operation. Affected TF releases are mitigated by a f...
