Division by zero in TFLite

Impact The implementation of fully connected layers in TFLite is vulnerable to a division by zero error: cc const int batchsize = inputsize / filter-dims-data1; An attacker can craft a model such that filter-dims-data1 is 0. Patches We have patched the issue in GitHub commit...

NPE in TFLite

Impact The implementation of SVDF in TFLite is vulnerable to a null pointer error: cc TfLiteTensor state = GetVariableInputcontext, node, kStateTensor; // ... GetTensorDatastate The GetVariableInput function can return a null pointer but GetTensorData assumes that the argument is always a valid...

Use of unitialized value in TFLite

Impact All TFLite operations that use quantization can be made to use unitialized values. For example: cc const auto affinequantization = reinterpretcast filter-quantization.params; The issue stems from the fact that quantization.params is only valid if quantization.type is different that...

FPE in TFLite pooling operations

Impact The implementations of pooling in TFLite are vulnerable to division by 0 errors as there are no checks for divisors not being 0. Patches We have patched the issue in GitHub commit dfa22b348b70bb89d6d6ec0ff53973bacb4f4695. The fix will be included in TensorFlow 2.6.0. We will also cherrypic...
