"According to the versions of the golang packages installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :
- 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. (CVE-2022-41717)
