  • CVE-2018-8014: Fix insecure default CORS filter settings (bsc#1093697).
  • CVE-2018-8034: The host name verification when using TLS with the WebSocket client was missing. It is now enabled by default (bsc#1102379).
  • CVE-2018-8037: If an async request was completed by the application at the same time as the container triggered the async timeout, a race condition existed that could have resulted in a user seeing a response intended for a different user. An additional issue was present in the NIO and NIO2 connectors that did not correctly track the closure of the connection when an async request was completed by the application and timed out by the container at the same time. This could also have resulted in a user seeing a response intended for another user (bsc#1102410).

Bug fixes:
  • Avoid overwriting of customer's configuration during update (bsc#1067720)
