Security flaws were highlighted by Zimperium that affect the Amazon FreeRTOS TCP/IP Stack. These flaws only relate to Amazon FreeRTOS TCP/IP. It does not affect the SAFERTOS/ OPENRTOS kernel code.

All WHIS customers that have been affected by this issue have been informed. They have either received an update, or will do in the very near future.

As part of our strategic business alliance with Amazon Web Services (AWS), WHIS offers commercial licenses for Amazon FreeRTOS, including their TCP/IP stack. AWS have released a later version of the TCP/IP stack which addresses the items mentioned in this report. This later version of the TCP/IP Stack is now being distributed by WHIS under a commercial license.

We very much appreciate the work undertaken by Zimperium, and the advance notice they provided allowing us to inform our customer base before the release of this article.
