"According to the version of the samba packages installed, the EulerOS
installation on the remote host is affected by the following
vulnerability :
- A flaw was found in samba's DNS server. An
authenticated user could use this flaw to the RPC
server to crash. This RPC server, which also serves
protocols other than dnsserver, will be restarted after
a short delay, but it is easy for an authenticated non
administrative attacker to crash it again as soon as it
returns. The Samba DNS server itself will continue to
operate, but many RPC services will
not.(CVE-2020-14383)
