CVE-2022-21736 Undefined behavior in Tensorflow

Tensorflow is an Open Source Machine Learning Framework. The implementation of SparseTensorSliceDataset has an undefined behavior: under certain condition it can be made to dereference a nullptr value. The 3 input arguments to SparseTensorSliceDataset represent a sparse tensor. However, there are...

CVE-2022-23568

CVE-2022-23568 describes an integer overflow in TensorFlow’s AddManySparseToTensorsMap, causing a CHECK-fail when constructingTensorShape objects. The issue arises from insufficient validation of input tensor shapes and constructing large TensorShape with user-provided dimensions, enabling a deni...

CVE-2022-21731 Type confusion leading to segfault in Tensorflow

Tensorflow is an Open Source Machine Learning Framework. The implementation of shape inference for ConcatV2 can be used to trigger a denial of service attack via a segfault caused by a type confusion. The axis argument is translated into concatdim in the ConcatShapeHelper helper function. Then, a...

CVE-2022-21733 Memory exhaustion in Tensorflow

Tensorflow is an Open Source Machine Learning Framework. The implementation of StringNGrams can be used to trigger a denial of service attack by causing an out of memory condition after an integer overflow. We are missing a validation on padwitdh and that result in computing a negative value for...

CVE-2022-21733

TensorFlow StringNGrams vulnerability CVE-2022-21733 causes memory exhaustion (OOM) due to missing validation of pad_width, which can result in a negative ngram_width used during output allocation. Affects TensorFlow/StringNGrams path in multiple TF versions; remediation is to upgrade to TensorFl...

CVE-2022-21732 Memory exhaustion in Tensorflow

Tensorflow is an Open Source Machine Learning Framework. The implementation of ThreadPoolHandle can be used to trigger a denial of service attack by allocating too much memory. This is because the numthreads argument is only checked to not be negative, but there is no upper bound on its value. Th...

CVE-2022-21732

CVE-2022-21732 affects TensorFlow’s ThreadPoolHandle. The vulnerability stems from allowing an unbounded num_threads value (only checked to be non-negative), enabling memory exhaustion and a potential denial-of-service. A fix is available in TensorFlow 2.8.0, with cherry-picks to 2.7.1, 2.6.3 and...

CVE-2022-21728

Tensorflow is an Open Source Machine Learning Framework. The implementation of shape inference for ReverseSequence does not fully validate the value of batchdim and can result in a heap OOB read. There is a check to make sure the value of batchdim does not go over the rank of the input, but there...

CVE-2022-21730

Tensorflow is an Open Source Machine Learning Framework. The implementation of FractionalAvgPoolGrad does not consider cases where the input tensors are invalid allowing an attacker to read from outside of bounds of heap. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this...

CVE-2022-21727

Tensorflow is an Open Source Machine Learning Framework. The implementation of shape inference for Dequantize is vulnerable to an integer overflow weakness. The axis argument can be -1 the default value for the optional argument or any other positive value at most the number of dimensions of the...
