A use of uninitialized value vulnerability in Tensorflow

Impact TensorFlow's Grappler optimizer has a use of unitialized variable: cc const NodeDef dequeuenode; for const auto& trainnode : trainnodes if IsDequeueOptrainnode dequeuenode = trainnode; break; if dequeuenode ... If the trainnodes vector obtained from the saved model that gets optimized does...

Code injection in `saved_model_cli`

Impact TensorFlow's savedmodelcli tool is vulnerable to a code injection as it calls eval on user supplied strings python def preprocessinputexprsargstringinputexprsstr: ... for inputraw in filterbool, inputexprsstr.split';': ... inputkey, expr = inputraw.split'=', 1 inputdictinputkey = evalexpr...

Heap out of bounds access in sparse reduction operations

Impact The implementation of sparse reduction operations in TensorFlow can trigger accesses outside of bounds of heap allocated data: python import tensorflow as tf x = tf.SparseTensor indices=773, 773, 773, 773, 773, 773, values=1, 1, denseshape=337, 337, 337 tf.sparse.reducesumx, 1 The...

Floating point exception in `SparseDenseCwiseDiv`

Impact The implementation of tf.rawops.SparseDenseCwiseDiv is vulnerable to a division by 0 error: python import tensorflow as tf import numpy as np tf.rawops.SparseDenseCwiseDiv spindices=np.array4, spvalues=np.array-400, spshape=np.array647., dense=np.array0 The implementation uses a common cla...

GHSA-HP4C-X6R7-6555 Floating point exception in `SparseDenseCwiseDiv`

Impact The implementation of tf.rawops.SparseDenseCwiseDiv is vulnerable to a division by 0 error: python import tensorflow as tf import numpy as np tf.rawops.SparseDenseCwiseDiv spindices=np.array4, spvalues=np.array-400, spshape=np.array647., dense=np.array0 The implementation uses a common cla...

Division by 0 in `ResourceScatterDiv`

Impact The implementation of tf.rawops.ResourceScatterDiv is vulnerable to a division by 0 error: python import tensorflow as tf v= tf.Variable1,2,3 tf.rawops.ResourceScatterDiv resource=v.handle, indices=1, updates=0 The implementation uses a common class for all binary operations but fails to...

Null pointer dereference in `MatrixDiagPartOp`

Impact 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: python import tensorflow as tf tf.rawops.MatrixDiagPartV2...

GHSA-HPV4-7P9C-MVFR Heap buffer overflow in `FractionalAvgPoolGrad`

Impact The implementation for tf.rawops.FractionalAvgPoolGrad can be tricked into accessing data outside of bounds of heap allocated buffers: python import tensorflow as tf tf.rawops.FractionalAvgPoolGrad originputtensorshape=0,1,2,3, outbackprop = np.array541,541,541,541, rowpoolingsequence=0, 0...

Heap OOB in `ResourceScatterUpdate`

Impact An attacker can trigger a read from outside of bounds of heap allocated data by sending invalid arguments to tf.rawops.ResourceScatterUpdate: python import tensorflow as tf v = tf.Variableb'vvv' tf.rawops.ResourceScatterUpdate resource=v.handle, indices=0, updates='1', '2', '3', '4', '5' T...

Crash caused by integer conversion to unsigned

Impact An attacker can cause a denial of service in boostedtreescreatequantilestreamresource by using negative arguments: python import tensorflow as tf from tensorflow.python.ops import genboostedtreesops import numpy as np v= tf.Variable0.0, 0.0, 0.0, 0.0, 0.0...

Reference binding to nullptr in `RaggedTensorToVariant`

Impact An attacker can cause undefined behavior via binding a reference to null pointer in tf.rawops.RaggedTensorToVariant: python import tensorflow as tf tf.rawops.RaggedTensorToVariant rtnestedsplits=, rtdensevalues=1,2,3, batchedinput=True The implementation has an incomplete validation of the...

FPE in `tf.raw_ops.UnravelIndex`

Impact An attacker can cause denial of service in applications serving models using tf.rawops.UnravelIndex by triggering a division by 0: python import tensorflow as tf tf.rawops.UnravelIndexindices=-1, dims=1,0,2 The implementation does not check that the tensor subsumed by dims is not empty...
