PYSEC-2021-571

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can cause undefined behavior via binding a reference to null pointer in all operations of type tf.rawops.MatrixSetDiagV. The implementation has incomplete validation that the value of k is a...

PYSEC-2021-575

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can generate undefined behavior via a reference binding to nullptr in BoostedTreesCalculateBestGainsPerFeature and similar attack can occur in BoostedTreesCalculateBestFeatureSplitV2. The...

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

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-2021-37641

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-2021-37664

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can read from outside of bounds of heap allocated data by sending specially crafted illegal arguments to BoostedTreesSparseCalculateBestFeatureSplit. The implementation needs to validate that...

CVE-2021-37655 Heap OOB in `ResourceScatterUpdate` in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can trigger a read from outside of bounds of heap allocated data by sending invalid arguments to tf.rawops.ResourceScatterUpdate. The implementation has an incomplete validation of the...

CVE-2021-37649

TensorFlow is an end-to-end open source platform for machine learning. The code for tf.rawops.UncompressElement can be made to trigger a null pointer dereference. The implementation obtains a pointer to a CompressedElement from a Variant tensor and then proceeds to dereference it for decompressin...

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...

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-2021-259

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. The implementation was accessing the size of a buffer obtained from the return of a separate function...

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-2021-265

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-2021-37637

CVE-2021-37637 is a TensorFlow null pointer dereference in tf.raw_ops.CompressElement triggered by invalid input. The issue occurred when code accessed a buffer size before validating the buffer, and has been patched in GitHub commit 5dc7f6981fdaf74c8c5be41f393df705841fb7c5. The fix will be in Te...

CVE-2021-37653

TensorFlow is an end-to-end open source platform for machine learning. In affected versions an attacker can trigger a crash via a floating point exception in tf.rawops.ResourceGather. The implementation computes the value of a value, batchsize, and then divides by it without checking that this...

CVE-2021-37642

TensorFlow is an end-to-end open source platform for machine learning. In affected versions the implementation of tf.rawops.ResourceScatterDiv 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...
