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.
