PYSEC-2021-752

TensorFlow is an end-to-end open source platform for machine learning. In affected versions 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. The implementation directly reads the first...

CVE-2021-37646

CVE-2021-37646 affects TensorFlow: the StringNGrams implementation can overflow when converting a negative, signed ngram_width to an unsigned size during a reserve call, enabling a potential denial-of-service condition. The root cause is a signed-to-unsigned conversion in TF’s string buffer alloc...

CVE-2021-37646 Bad alloc in `StringNGrams` caused by integer conversion in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. In affected versions 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. The...

CVE-2021-37645 Integer overflow due to conversion to unsigned in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. In affected versions 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 thi...

CVE-2021-37644 `std::abort` raised from `TensorListReserve` in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. In affected versions 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. The...

CVE-2021-37654 Heap OOB and CHECK fail in `ResourceGather` in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can trigger a crash via a CHECK-fail in debug builds of TensorFlow using tf.rawops.ResourceGather or a read from outside the bounds of heap allocated data in the same API in a release build. Th...

CVE-2021-37655

CVE-2021-37655 describes a heap-based read out of bounds in TensorFlow caused by incomplete validation when updating a resource with tf.raw_ops.ResourceScatterUpdate. The issue stems from validating the relationship between the shapes of indices and updates (only divisibility checked instead of p...

CVE-2021-37638

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...

Null pointer dereference

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...

Null pointer dereference

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...

PYSEC-2021-758

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-2021-552

TensorFlow is an end-to-end open source platform for machine learning. When restoring tensors via raw APIs, if the tensor name is not provided, TensorFlow can be tricked into dereferencing a null pointer. Alternatively, attackers can read memory outside the bounds of heap allocated data by...

PYSEC-2021-748

TensorFlow is an end-to-end open source platform for machine learning. It is possible to trigger a null pointer dereference in TensorFlow by passing an invalid input to tf.rawops.CompressElement.
