TensorFlow is an end-to-end open source platform for machine learning. The fix for CVE-2020-15209https://vulners.com/cve/CVE-2020-15209 missed the case when the target shape of Reshape operator is given by the elements of a 1-D tensor. As such, the fix for the...

PYSEC-2021-449

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 denial of service via a FPE runtime error in tf.rawops.SparseMatMul. The division by 0 occurs deep in Eigen code because the b tensor is empty. The fix will be included in TensorFlow 2.5.0. We will also...

TensorFlow is an end-to-end open source platform for machine learning. An attacker can force accesses outside the bounds of heap allocated arrays by passing in invalid tensor values to tf.rawops.RaggedCross. 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-2021-29514

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...

CVE-2021-29515 Reference binding to null pointer in `MatrixDiag*` ops

TensorFlow is an end-to-end open source platform for machine learning. The implementation of MatrixDiag operationshttps://github.com/tensorflow/tensorflow/blob/4c4f420e68f1cfaf8f4b6e8e3eb857e9e4c3ff33/tensorflow/core/kernels/linalg/matrixdiagop.ccL195-L197 does not validate that the tensor...

CVE-2021-29515

The CVE-2021-29515 issue affects TensorFlow MatrixDiag* ops: input tensors are not validated to be non-empty, which can lead to a null pointer dereference. The root cause is in MatrixDiagV2/V3 path handling inputs, and patches fix the issue (commit a7116dd39…) with the fix slated for TensorFlow 2...
