ArduinoBLE enables Bluetooth Low Energy connectivity on certain Arduino models. Versions prior to 2.0.2 contain a missing bounds check in the ATT layer write request handler that allows a remote, unauthenticated BLE client to corrupt memory in the ATTClass global object. Devices running ArduinoBLE with one or more characteristics configured with the BLEEncryption property are affected. The fix is included starting from the 2.0.2 release.
