 Package : golang-websocket Version : 1.4.0-1+deb10u1 CVE ID : CVE-2020-27813

 An integer overflow vulnerability exists in golang-websocket, a Go package implementing the WebSocket protocol connection. An attacker would use this flaw to cause a denial of service attack on an HTTP Server allowing websocket connections.

 The following reverse-dependencies have been rebuilt against the new golang- websocket version: hugo and gitlab-workhorse

 For Debian 10 buster, this problem has been fixed in version 1.4.0-1+deb10u1.

 We recommend that you upgrade your golang-websocket packages.
