BIT-TENSORFLOW-2022-29201 Missing validation in `QuantizedConv2D` results in undefined behavior in TensorFlow

TensorFlow is an open source platform for machine learning. Prior to versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4, the implementation of tf.rawops.QuantizedConv2D does not fully validate the input arguments. In this case, references get bound to nullptr for each argument that is empty. Versions 2.9.0,...

BIT-TENSORFLOW-2022-29202 Denial of service in TensorFlow due to lack of validation in `tf.ragged.constant`

TensorFlow is an open source platform for machine learning. Prior to versions 2.9.0, 2.8.1, 2.7.2, and 2.6.4, the implementation of tf.ragged.constant does not fully validate the input arguments. This results in a denial of service by consuming all available memory. Versions 2.9.0, 2.8.1, 2.7.2,...

BIT-TENSORFLOW-2022-35937 OOB read in `Gather_nd` op in TensorFlow Lite

TensorFlow is an open source platform for machine learning. The GatherNd function takes arguments that determine the sizes of inputs and outputs. If the inputs given are greater than or equal to the sizes of the outputs, an out-of-bounds memory read is triggered. This issue has been patched in...

BIT-TENSORFLOW-2022-35979 Segfault in `QuantizedRelu` and `QuantizedRelu6`

TensorFlow is an open source platform for machine learning. If QuantizedRelu or QuantizedRelu6 are given nonscalar inputs for minfeatures or maxfeatures, it results in a segfault that can be used to trigger a denial of service attack. We have patched the issue in GitHub commit...

BIT-TENSORFLOW-2022-35981 `CHECK` fail in `FractionalMaxPoolGrad` in TensorFlow

TensorFlow is an open source platform for machine learning. FractionalMaxPoolGrad validates its inputs with CHECK failures instead of with returning errors.

BIT-TENSORFLOW-2022-36016 `CHECK`-fail in `tensorflow::full_type::SubstituteFromAttrs` in TensorFlow

TensorFlow is an open source platform for machine learning. When tensorflow::fulltype::SubstituteFromAttrs receives a FullTypeDef& t that is not exactly three args, it triggers a CHECK-fail instead of returning a status. We have patched the issue in GitHub commit...

BIT-TENSORFLOW-2022-41884 Seg fault in `ndarray_tensor_bridge` due to zero and large inputs in Tensorflow

TensorFlow is an open source platform for machine learning. If a numpy array is created with a shape such that one element is zero and the others sum to a large number, an error will be raised. We have patched the issue in GitHub commit 2b56169c16e375c521a3bc8ea658811cc0793784. The fix will be...

BIT-TYPO3-2021-21338

TYPO3 is an open source PHP based web content management system. In TYPO3 before versions 6.2.57, 7.6.51, 8.7.40, 9.5.25, 10.4.14, 11.1.1 it has been discovered that Login Handling is susceptible to open redirection which allows attackers redirecting to arbitrary content, and conducting phishing...

BIT-TENSORFLOW-2022-41889 Segfault via invalid attributes in `pywrap_tfe_src.cc` in Tensorflow

TensorFlow is an open source platform for machine learning. If a list of quantized tensors is assigned to an attribute, the pywrap code fails to parse the tensor and returns a nullptr, which is not caught. An example can be seen in tf.compat.v1.extractvolumepatches by passing in quantized tensors...

BIT-TENSORFLOW-2022-41895 `MirrorPadGrad` heap out of bounds read in Tensorflow

TensorFlow is an open source platform for machine learning. If MirrorPadGrad is given outsize input paddings, TensorFlow will give a heap OOB error. We have patched the issue in GitHub commit 717ca98d8c3bba348ff62281fdf38dcb5ea1ec92. The fix will be included in TensorFlow 2.11. We will also...
