Out of bounds access in tensorflow-lite
Impact In TensorFlow Lite, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices for the tensors, indexing into an array of...
Null pointer dereference in tensorflow-lite
Impact A crafted TFLite model can force a node to have as input a tensor backed by a nullptr buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one. The runtime assumes that these buffers are written to before a...
Data corruption in tensorflow-lite
Impact When determining the common dimension size of two tensors, TFLite uses a DCHECK which is no-op outside of debug compilation modes: https://github.com/tensorflow/tensorflow/blob/0e68f4d3295eb0281a517c3662f6698992b7b2cf/tensorflow/lite/kernels/internal/types.hL437-L442 Since the function...
Segfault and data corruption in tensorflow-lite
Impact To mimic Python's indexing with negative values, TFLite uses ResolveAxis to convert negative values to positive indices. However, the only check that the converted index is now valid is only present in debug builds:...
Segfault in Tensorflow
Impact In eager mode, TensorFlow does not set the session state. Hence, calling tf.rawops.GetSessionHandle or tf.rawops.GetSessionHandleV2 results in a null pointer dereference:...
GHSA-G7P5-5759-QV46 Data leak in Tensorflow
Impact The datasplits argument of tf.rawops.StringNGrams lacks validation. This allows a user to pass values that can cause heap overflow errors and even leak contents of memory python tf.rawops.StringNGramsdata="aa", "bb", "cc", "dd", "ee", "ff", datasplits=0,8, separator=" ", ngramwidths=3,...

Denial of Service in Tensorflow
Impact 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:...
Integer truncation in Shard API usage
Impact The Shard API in TensorFlow expects the last argument to be a function taking two int64 i.e., long long arguments: https://github.com/tensorflow/tensorflow/blob/0e68f4d3295eb0281a517c3662f6698992b7b2cf/tensorflow/core/util/worksharder.hL59-L60 However, there are several places in TensorFlo...
Heap buffer overflow in Tensorflow
Impact 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. Hence, this code is prone to heap buffer overflow...
Heap buffer overflow in Tensorflow
Impact The implementation of SparseFillEmptyRowsGrad uses a double indexing pattern: https://github.com/tensorflow/tensorflow/blob/0e68f4d3295eb0281a517c3662f6698992b7b2cf/tensorflow/core/kernels/sparsefillemptyrowsop.ccL263-L269 It is possible for reverseindexmapi to be an index outside of bound...
Memory corruption in Tensorflow
Impact The implementation of dlpack.todlpack can be made to use uninitialized memory resulting in further memory corruption. This is because the pybind11 glue code assumes that the argument is a tensor:...
Segfault in Tensorflow
Impact 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. However, the eager runtime traverses all tensors in the output:...

GHSA-WMV4-5W76-VP9G Authorization Bypass in Spring Security
When using Spring Security's CAS Proxy ticket authentication a malicious CAS Service could trick another CAS Service into authenticating a proxy ticket that was not associated. This is due to the fact that the proxy ticket authentication uses the information from the HttpServletRequest which is...
