Root cause

Amazon Web Services (AWS) FreeRTOS through 1.3.1, FreeRTOS up to V10.0.1 (with FreeRTOS+TCP), and WITTENSTEIN WHIS Connect middleware TCP/IP component allow information disclosure during parsing of TCP options in prvCheckOptions.

Software

Name

FreeRTOS

Versions affected

1.3.1 - 10.0.1
