BIT-TENSORFLOW-2022-41908 `CHECK` fail via inputs in `PyFunc` in Tensorflow

TensorFlow is an open source platform for machine learning. An input token that is not a UTF-8 bytestring will trigger a CHECK fail in tf.rawops.PyFunc. We have patched the issue in GitHub commit 9f03a9d3bafe902c1e6beb105b2f24172f238645. The fix will be included in TensorFlow 2.11. We will also...

BIT-TENSORFLOW-2022-41909 Segfault in `CompositeTensorVariantToComponents` in Tensorflow

TensorFlow is an open source platform for machine learning. An input encoded that is not a valid CompositeTensorVariant tensor will trigger a segfault in tf.rawops.CompositeTensorVariantToComponents. We have patched the issue in GitHub commits bf594d08d377dc6a3354d9fdb494b32d45f91971 and...

BIT-TENSORFLOW-2022-41910 Heap out of bounds read in `QuantizeAndDequantizeV2` in Tensorflow

TensorFlow is an open source platform for machine learning. The function MakeGrapplerFunctionItem takes arguments that determine the sizes of inputs and outputs. If the inputs given are greater than or equal to the sizes of the outputs, an out-of-bounds memory read or a crash is triggered. We hav...

BIT-TENSORFLOW-2022-41911 Invalid char to bool conversion when printing a tensor in Tensorflow

TensorFlow is an open source platform for machine learning. When printing a tensor, we get it's data as a const char array since that's the underlying storage and then we typecast it to the element type. However, conversions from char to bool are undefined if the char is not 0 or 1, so...

FreeBSD : py-tflite -- buffer overflow vulnerability (326b2f3e-6fc7-4661-955d-a772760db9cf)
