TensorFlow is an end-to-end open source platform for machine learning. The implementation of TrySimplifyhttps://github.com/tensorflow/tensorflow/blob/c22d88d6ff33031aa113e48aa3fc9aa74ed79595/tensorflow/core/grappler/optimizers/arithmeticoptimizer.ccL390-L401 has undefined behavior due to...

PYSEC-2021-250

TensorFlow is an end-to-end open source platform for machine learning. Incomplete validation in tf.rawops.CTCLoss allows an attacker to trigger an OOB read from heap. The fix will be included in TensorFlow 2.5.0. We will also cherrypick these commits on TensorFlow 2.4.2, TensorFlow 2.3.3,...

PYSEC-2021-450

TensorFlow is an end-to-end open source platform for machine learning. The tf.rawops.Conv3DBackprop operations fail to validate that the input tensors are not empty. In turn, this would result in a division by 0. This is because the...

PYSEC-2021-538

TensorFlow is an end-to-end open source platform for machine learning. The validation in tf.rawops.QuantizeAndDequantizeV2 allows invalid values for axis argument:. The...

PYSEC-2021-647

TensorFlow is an end-to-end open source platform for machine learning. Specifying a negative dense shape in tf.rawops.SparseCountSparseOutput results in a segmentation fault being thrown out from the standard library as std::vector invariants are broken. This is because the...

PYSEC-2021-457

TensorFlow is an end-to-end open source platform for machine learning. An attacker can trigger a heap buffer overflow in tf.rawops.QuantizedResizeBilinear by manipulating input values so that float rounding results in off-by-one error in accessing image elements. This is because the...

TensorFlow is an end-to-end open source platform for machine learning. An attacker can cause a segfault and denial of service via accessing data outside of bounds in tf.rawops.QuantizedBatchNormWithGlobalNormalization. This is because the...

CVE-2021-29513

TensorFlow vulnerability CVE-2021-29513 arises when calling TF operations with tensors of non-numeric types, causing a null pointer dereference due to a type confusion in the Python-to-C++ array conversion (ndarray_tensor.cc). Root cause: PyArray_DESCR_to_TF_DataType path can dereference NULL in ...

CVE-2021-29513 Type confusion during tensor casts lead to dereferencing null pointers

TensorFlow is an end-to-end open source platform for machine learning. Calling TF operations with tensors of non-numeric types when the operations expect numeric tensors result in null pointer dereferences. The conversion from Python array to C++...

CVE-2021-29514 Heap out of bounds write in `RaggedBinCount`

TensorFlow is an end-to-end open source platform for machine learning. If the splits argument of RaggedBincount does not specify a valid SparseTensorhttps://www.tensorflow.org/apidocs/python/tf/sparse/SparseTensor, then an attacker can trigger a heap buffer overflow. This will cause a read from...

CVE-2021-29514

TensorFlow RaggedBincount vulnerability (CVE-2021-29514) in the RaggedBincount kernel can cause a heap out-of-bounds write when the splits argument references an invalid SparseTensor, leading to a write at out(-1, bin). The issue is triggered by setting splits(0) to 7, causing batch_idx to remain...
