SWFTools swfc-history.c Denial of Service Vulnerability

SWFTools is a set of utilities for working with Adobe Flash files SWF files. A denial of service vulnerability exists in SWFTools version v0.9.2, which originates from a function statefree in file swftools/src/swfc-history.c that contains a segmentation conflict. An attacker can exploit this...

BIT-TENSORFLOW-2020-15190 Segfault in Tensorflow

In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, the tf.rawops.Switch operation takes as input a tensor and a boolean and outputs two tensors. Depending on the boolean value, one of the tensors is exactly the input tensor whereas the other one should be an empty tensor. Howeve...

BIT-TENSORFLOW-2020-15200 Segfault in Tensorflow

In Tensorflow before version 2.3.1, the RaggedCountSparseOutput implementation does not validate that the input arguments form a valid ragged tensor. In particular, there is no validation that the values in the splits tensor generate a valid partitioning of the values tensor. Thus, the code sets ...

BIT-TENSORFLOW-2020-15203 Denial of Service in Tensorflow

In Tensorflow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, by controlling the fill argument of tf.strings.asstring, a malicious attacker is able to trigger a format string vulnerability due to the way the internal format use in a printf call is constructed. This may result in segmentati...

BIT-TENSORFLOW-2020-15204 Segfault in Tensorflow

In eager mode, TensorFlow before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1 does not set the session state. Hence, calling tf.rawops.GetSessionHandle or tf.rawops.GetSessionHandleV2 results in a null pointer dereference In linked snippet, in eager mode, ctx-sessionstate returns nullptr. Since...

BIT-TENSORFLOW-2020-15210 Segmentation fault in tensorflow-lite

In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, if a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. We have patched the issue in d58c96946b a...

BIT-TENSORFLOW-2020-15214 Out of bounds write in tensorflow-lite

In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger a write out bounds / segmentation fault if the segment ids are not sorted. Code assumes that the segment ids are in increasing order, using the last element of the tensor holding them to determine the...

BIT-TENSORFLOW-2020-15266 Undefined behavior in Tensorflow

In Tensorflow before version 2.4.0, when the boxes argument of tf.image.cropandresize has a very large value, the CPU kernel implementation receives it as a C++ nan floating point value. Attempting to operate on this is undefined behavior which later produces a segmentation fault. The issue is...

BIT-TENSORFLOW-2020-26268 Write to immutable memory region in TensorFlow

In affected versions of TensorFlow the tf.rawops.ImmutableConst operation returns a constant tensor created from a memory mapped file which is assumed immutable. However, if the type of the tensor is not an integral type, the operation crashes the Python interpreter as it tries to write to the...

BIT-TENSORFLOW-2020-5215 Segmentation faultin TensorFlow when converting a Python string to tf.float16

In TensorFlow before 1.15.2 and 2.0.1, converting a string from Python to a tf.float16 value results in a segmentation fault in eager mode as the format checks for this use case are only in the graph mode. This issue can lead to denial of service in inference/training where a malicious attacker c...

BIT-TENSORFLOW-2021-29521 Segfault in SparseCountSparseOutput

TensorFlow is an end-to-end open source platform for machine learning. Specifying a negative dense shape in tf.rawops.SparseCountSparseOutput results in a segmentation fault being thrown out from the standard library as std::vector invariants are broken. This is because the...

BIT-TENSORFLOW-2021-29581 Segfault in `CTCBeamSearchDecoder`

TensorFlow is an end-to-end open source platform for machine learning. Due to lack of validation in tf.rawops.CTCBeamSearchDecoder, an attacker can trigger denial of service via segmentation faults. The...

BIT-TENSORFLOW-2021-37650 Segfault and heap buffer overflow in `{Experimental,}DatasetToTFRecord` in TensorFlow

TensorFlow is an end-to-end open source platform for machine learning. In affected versions the implementation for tf.rawops.ExperimentalDatasetToTFRecord and tf.rawops.DatasetToTFRecord can trigger heap buffer overflow and segmentation fault. The implementation assumes that all records in the...
