    Summary: Updated qtwebsockets5 packages fix a security vulnerability

    Details: In Qt through 5.14.1, the WebSocket implementation accepts up to 2GB for frames and 2GB for messages. Smaller limits cannot be configured. This makes it easier for attackers to cause a denial of service (memory consumption) (CVE-2018-21035).
