NVD Description

Note: Versions mentioned in the description apply only to the upstream weldr-client package and not the weldr-client package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.
