TensorFlow through 2.5.0 allows attackers to overwrite arbitrary files via a crafted archive when tf.keras.utils.get_file is used with extract=True. NOTE: the vendor's position is that tf.keras.utils.get_file is not intended for untrusted archives ** EN DISPUTA ** TensorFlow versiones hasta 2.5.0, permite a atacantes sobrescribir archivos arbitrarios por medio de un archivo diseñado cuando se usa la función tf.keras.utils.get_file con extract=True. NOTA: la posición del proveedor es que la función tf.keras.utils.get_file no está pensado para archivos no confiables • https://github.com/miguelc49/CVE-2021-35958-2 https://github.com/miguelc49/CVE-2021-35958-1 https://docs.python.org/3/library/tarfile.html#tarfile.TarFile.extractall https://github.com/tensorflow/tensorflow/blob/b8cad4c631096a34461ff8a07840d5f4d123ce32/tensorflow/python/keras/README.md https://github.com/tensorflow/tensorflow/blob/b8cad4c631096a34461ff8a07840d5f4d123ce32/tensorflow/python/keras/utils/data_utils.py#L137 https://keras.io/api https://vuln.ryotak.me/advisories/52 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 1CVE-2021-29513 – Type confusion during tensor casts lead to dereferencing null pointers
https://notcve.org/view.php?id=CVE-2021-29513
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++ array(https://github.com/tensorflow/tensorflow/blob/ff70c47a396ef1e3cb73c90513da4f5cb71bebba/tensorflow/python/lib/core/ndarray_tensor.cc#L113-L169) is vulnerable to a type confusion. The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range. • https://github.com/tensorflow/tensorflow/commit/030af767d357d1b4088c4a25c72cb3906abac489 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-452g-f7fp-9jf7 • CWE-476: NULL Pointer Dereference CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 1CVE-2021-29514 – Heap out of bounds write in `RaggedBinCount`
https://notcve.org/view.php?id=CVE-2021-29514
TensorFlow is an end-to-end open source platform for machine learning. If the `splits` argument of `RaggedBincount` does not specify a valid `SparseTensor`(https://www.tensorflow.org/api_docs/python/tf/sparse/SparseTensor), then an attacker can trigger a heap buffer overflow. This will cause a read from outside the bounds of the `splits` tensor buffer in the implementation of the `RaggedBincount` op(https://github.com/tensorflow/tensorflow/blob/8b677d79167799f71c42fd3fa074476e0295413a/tensorflow/core/kernels/bincount_op.cc#L430-L446). Before the `for` loop, `batch_idx` is set to 0. The attacker sets `splits(0)` to be 7, hence the `while` loop does not execute and `batch_idx` remains 0. • https://github.com/tensorflow/tensorflow/commit/eebb96c2830d48597d055d247c0e9aebaea94cd5 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-8h46-5m9h-7553 • CWE-787: Out-of-bounds Write •

CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 1CVE-2021-29516 – Null pointer dereference via invalid Ragged Tensors
https://notcve.org/view.php?id=CVE-2021-29516
TensorFlow is an end-to-end open source platform for machine learning. Calling `tf.raw_ops.RaggedTensorToVariant` with arguments specifying an invalid ragged tensor results in a null pointer dereference. The implementation of `RaggedTensorToVariant` operations(https://github.com/tensorflow/tensorflow/blob/904b3926ed1c6c70380d5313d282d248a776baa1/tensorflow/core/kernels/ragged_tensor_to_variant_op.cc#L39-L40) does not validate that the ragged tensor argument is non-empty. Since `batched_ragged` contains no elements, `batched_ragged.splits` is a null vector, thus `batched_ragged.splits(0)` will result in dereferencing `nullptr`. The fix will be included in TensorFlow 2.5.0. • https://github.com/tensorflow/tensorflow/commit/b055b9c474cd376259dde8779908f9eeaf097d93 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-84mw-34w6-2q43 • CWE-476: NULL Pointer Dereference •
