CVE-2020-14383  (opens in a new tab)

How to fix?

Upgrade Debian:10 samba to version 2:4.9.5+dfsg-5+deb10u5 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream samba package and not the samba package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

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.
