Critical Cosmos Database Flaw Affected Thousands of Microsoft Azure Customers

Cloud infrastructure security company Wiz on Thursday revealed details of a now-fixed Azure Cosmos database vulnerability that could have been potentially exploited to grant any Azure user full admin access to other customers' database instances without any authorization. The flaw, which grants...

XStream can cause a Denial of Service

Impact The vulnerability may allow a remote attacker to allocate 100% CPU time on the target system depending on CPU type or parallel execution of such a payload resulting in a denial of service only by manipulating the processed input stream. No user is affected, who followed the recommendation ...

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...

Null pointer dereference in `CompressElement`

Impact It is possible to trigger a null pointer dereference in TensorFlow by passing an invalid input to tf.rawops.CompressElement: python import tensorflow as tf tf.rawops.CompressElementcomponents= The implementation was accessing the size of a buffer obtained from the return of a separate...

Null pointer dereference in `RaggedTensorToTensor`

Impact Sending invalid argument for rowpartitiontypes of tf.rawops.RaggedTensorToTensor API results in a null pointer dereference and undefined behavior: python import tensorflow as tf tf.rawops.RaggedTensorToTensor shape=1, values=10, defaultvalue=21, rowpartitiontensors=tf.constant0,0,0,0,...

Null pointer dereference and heap OOB read in operations restoring tensors

Impact When restoring tensors via raw APIs, if the tensor name is not provided, TensorFlow can be tricked into dereferencing a null pointer: python import tensorflow as tf tf.rawops.Restore filepattern='/tmp', tensorname=, defaultvalue=21, dt=tf.int, preferredshard=1 The same undefined behavior c...

Integer division by 0 in sparse reshaping

Impact The implementation of tf.rawops.SparseReshape can be made to trigger an integral division by 0 exception: python import tensorflow as tf tf.rawops.SparseReshape inputindices = np.ones1,3, inputshape = np.array1,1,0, newshape = np.array1,0 The implementation calls the reshaping functor...

Heap OOB in `RaggedGather`

Impact If the arguments to tf.rawops.RaggedGather don't determine a valid ragged tensor code can trigger a read from outside of bounds of heap allocated buffers. python import tensorflow as tf tf.rawops.RaggedGather paramsnestedsplits = 0,0,0, paramsdensevalues = 1,1, indices = 0,0,9,0,0,...

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...

`std::abort` raised from `TensorListReserve`

Impact Providing a negative element to numelements list argument of tf.rawops.TensorListReserve causes the runtime to abort the process due to reallocating a std::vector to have a negative number of elements: python import tensorflow as tf tf.rawops.TensorListReserve elementshape = tf.constant1,...

Integer overflow due to conversion to unsigned

Impact The implementation of tf.rawops.QuantizeAndDequantizeV4Grad is vulnerable to an integer overflow issue caused by converting a signed integer value to an unsigned one and then allocating memory based on this value. python import tensorflow as tf tf.rawops.QuantizeAndDequantizeV4Grad...

Bad alloc in `StringNGrams` caused by integer conversion

Impact The implementation of tf.rawops.StringNGrams is vulnerable to an integer overflow issue caused by converting a signed integer value to an unsigned one and then allocating memory based on this value. python import tensorflow as tf tf.rawops.StringNGrams data='','', datasplits=0,2, separator...

Null pointer dereference in `SparseTensorSliceDataset`

Impact 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: python import tensorflow as tf tf.rawops.SparseTensorSliceDataset indices=,,, values=1,2,3, denseshape=3,3 The...

Null pointer dereference in `UncompressElement`

Impact The code for tf.rawops.UncompressElement can be made to trigger a null pointer dereference: python import tensorflow as tf data = tf.data.Dataset.fromtensors0.0 tf.rawops.UncompressElement compressed=tf.data.experimental.tovariantdata, outputtypes=tf.int64, outputshapes=2 The implementatio...
