The open-source operating system that powers most of the small microprocessors and microcontrollers in smart homes and critical infrastructure systems has 13 vulnerabilities, a third of them allowing remote code execution. The vulnerabilities are in the TCP/IP stack and affect the FreeRTOS derivation maintained by Amazon and the OpenRTOS and SafeRTOS maintained by WITTENSTEIN high integrity systems. Amazon has been notified of the situation and the company responded by releasing patches to mitigate the problems.
