CVE-2020-25684 [LOW] CWE-358 CVE-2020-25684: A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmas A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in the forward.c:reply_query() if the reply destination address/port is used by the pending forwarded queries. However, it does not use the address/port to retrieve the exact forwarded query, substantially reducing the number of attempts an atta
