CVSS: 4.3EPSS: 0%CPEs: 3EXPL: 1CVE-2020-15192 – Memory leak in Tensorflow
https://notcve.org/view.php?id=CVE-2020-15192
In Tensorflow before versions 2.2.1 and 2.3.1, if a user passes a list of strings to `dlpack.to_dlpack` there is a memory leak following an expected validation failure. The issue occurs because the `status` argument during validation failures is not properly checked. Since each of the above methods can return an error status, the `status` value must be checked before continuing. The issue is patched in commit 22e07fb204386768e5bcbea563641ea11f96ceb8 and is released in TensorFlow versions 2.2.1, or 2.3.1. En Tensorflow versiones anteriores a 2.2.1 y 2.3.1, si un usuario pasa una lista de cadenas hacia "dlpack.to_dlpack", se presenta una pérdida de memoria después de un fallo de comprobación esperada. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8 https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-8fxw-76px-3rxv • CWE-20: Improper Input Validation •
CVSS: 7.1EPSS: 0%CPEs: 3EXPL: 1CVE-2020-15193 – Memory corruption in Tensorflow
https://notcve.org/view.php?id=CVE-2020-15193
In Tensorflow before versions 2.2.1 and 2.3.1, the implementation of `dlpack.to_dlpack` can be made to use uninitialized memory resulting in further memory corruption. This is because the pybind11 glue code assumes that the argument is a tensor. However, there is nothing stopping users from passing in a Python object instead of a tensor. The uninitialized memory address is due to a `reinterpret_cast` Since the `PyObject` is a Python object, not a TensorFlow Tensor, the cast to `EagerTensor` fails. The issue is patched in commit 22e07fb204386768e5bcbea563641ea11f96ceb8 and is released in TensorFlow versions 2.2.1, or 2.3.1. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html https://github.com/tensorflow/tensorflow/commit/22e07fb204386768e5bcbea563641ea11f96ceb8 https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-rjjg-hgv6-h69v • CWE-908: Use of Uninitialized Resource •
CVSS: 5.3EPSS: 0%CPEs: 6EXPL: 1CVE-2020-15194 – Denial of Service in Tensorflow
https://notcve.org/view.php?id=CVE-2020-15194
In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the `SparseFillEmptyRowsGrad` implementation has incomplete validation of the shapes of its arguments. Although `reverse_index_map_t` and `grad_values_t` are accessed in a similar pattern, only `reverse_index_map_t` is validated to be of proper shape. Hence, malicious users can pass a bad `grad_values_t` to trigger an assertion failure in `vec`, causing denial of service in serving installations. The issue is patched in commit 390611e0d45c5793c7066110af37c8514e6a6c54, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1." En Tensorflow versiones anteriores a 1.15.4, 2.0.3, 2.1.2, 2.2.1 y 2.3.1, la implementación de "SparseFillEmptyRowsGrad" presenta una comprobación incompleta de las formas de sus argumentos. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html https://github.com/tensorflow/tensorflow/commit/390611e0d45c5793c7066110af37c8514e6a6c54 https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-9mqp-7v2h-2382 • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •
CVSS: 8.8EPSS: 0%CPEs: 6EXPL: 1CVE-2020-15195 – Heap buffer overflow in Tensorflow
https://notcve.org/view.php?id=CVE-2020-15195
In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the implementation of `SparseFillEmptyRowsGrad` uses a double indexing pattern. It is possible for `reverse_index_map(i)` to be an index outside of bounds of `grad_values`, thus resulting in a heap buffer overflow. The issue is patched in commit 390611e0d45c5793c7066110af37c8514e6a6c54, and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1. En Tensorflow versiones anteriores a 1.15.4, 2.0.3, 2.1.2, 2.2.1 y 2.3.1, la implementación de "SparseFillEmptyRowsGrad" usa un patrón de indexación doble. Es posible que "reverse_index_map (i)" sea un índice fuera de los límites de "grad_values", lo que resulta en un desbordamiento del búfer de la pila. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html https://github.com/tensorflow/tensorflow/commit/390611e0d45c5793c7066110af37c8514e6a6c54 https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-63xm-rx5p-xvqr • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 5.3EPSS: 0%CPEs: 6EXPL: 1CVE-2020-15190 – Segfault in Tensorflow
https://notcve.org/view.php?id=CVE-2020-15190
In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the `tf.raw_ops.Switch` operation takes as input a tensor and a boolean and outputs two tensors. Depending on the boolean value, one of the tensors is exactly the input tensor whereas the other one should be an empty tensor. However, the eager runtime traverses all tensors in the output. Since only one of the tensors is defined, the other one is `nullptr`, hence we are binding a reference to `nullptr`. This is undefined behavior and reported as an error if compiling with `-fsanitize=null`. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00065.html https://github.com/tensorflow/tensorflow/commit/da8558533d925694483d2c136a9220d6d49d843c https://github.com/tensorflow/tensorflow/releases/tag/v2.3.1 https://github.com/tensorflow/tensorflow/security/advisories/GHSA-4g9f-63rx-5cw4 • CWE-20: Improper Input Validation CWE-476: NULL Pointer Dereference •
