TensorFlow is an end-to-end open source platform for machine learning. When a user does not supply arguments that determine a valid sparse tensor, tf.rawops.SparseTensorSliceDataset implementation can be made to dereference a null pointer. The implementation has some argument validation but fails...

PYSEC-2021-260

TensorFlow is an end-to-end open source platform for machine learning. Sending invalid argument for rowpartitiontypes of tf.rawops.RaggedTensorToTensor API results in a null pointer dereference and undefined behavior. The implementation accesses the first element of a user supplied list of values...

CVE-2021-37643

TensorFlow is an end-to-end open source platform for machine learning. If a user does not provide a valid padding value to tf.rawops.MatrixDiagPartOp, then the code triggers a null pointer dereference if input is empty or produces invalid behavior, ignoring all values after the first. The...

CVE-2021-37636

TensorFlow is an end-to-end open source platform for machine learning. In affected versions the implementation of tf.rawops.SparseDenseCwiseDiv is vulnerable to a division by 0 error. The implementation uses a common class for all binary operations but fails to treat the division by 0 case...

GHSA-MQ5C-PRH3-3F3H Invalid validation in `QuantizeAndDequantizeV2`

Impact The validation in tf.rawops.QuantizeAndDequantizeV2 allows invalid values for axis argument: python import tensorflow as tf inputtensor = tf.constant0.0, shape=1, dtype=float inputmin = tf.constant-10.0 inputmax = tf.constant-10.0 tf.rawops.QuantizeAndDequantizeV2 input=inputtensor,...

GHSA-4VRF-FF7V-HPGR Division by zero in TFLite's implementation of `EmbeddingLookup`

The implementation of the EmbeddingLookup TFLite operator is vulnerable to a division by zero error: cc const int rowsize = SizeOfDimensionvalue, 0; const int rowbytes = value-bytes / rowsize; An attacker can craft a model such that the first dimension of the value input is 0. Patches We have...

GHSA-3QGW-P4FM-X7GF Division by zero in TFLite's convolution code

Impact TFLite's convolution code has multiple division where the divisor is controlled by the user and not checked to be non-zero. For example: cc const int inputsize = NumElementsinput / SizeOfDimensioninput, 0; Patches We have patched the issue in GitHub commit...

GHSA-VFR4-X8J2-3RF9 Division by zero in TFLite's implementation of `TransposeConv`

Impact The optimized implementation of the TransposeConv TFLite operator is vulnerable to a division by zero error: cc int heightcol = height + padt + padb - filterh / strideh + 1; int widthcol = width + padl + padr - filterw / stridew + 1; An attacker can craft a model such that strideh,w values...

GHSA-4278-2V5V-65R4 Heap buffer overflow in `RaggedBinCount`

Impact If the splits argument of RaggedBincount does not specify a valid SparseTensor, then an attacker can trigger a heap buffer overflow: python import tensorflow as tf tf.rawops.RaggedBincountsplits=0, values=1,1,1,1,1, size=5, weights=1,2,3,4, binaryoutput=False This will cause a read from...
