CVE-2020-25686 [LOW] CVE-2020-25686: A flaw was found in dnsmasq before version 2.83. When receiving a query, dnsmasq does not check for A flaw was found in dnsmasq before version 2.83. When receiving a query, dnsmasq does not check for an existing pending request for the same name and forwards a new request. By default, a maximum of 150 pending queries can be sent to upstream servers, so there can be at most 150 queries for the same name. This flaw allows an off-path attacker on the network to

CVE-2020-25685 [LOW] CVE-2020-25685: 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 forward.c:reply_query(), which is the forwarded query that matches the reply, by only using a weak hash of the query name. Due to the weak hash (CRC32 when dnsmasq is compiled without DNSSEC, SHA-1 when it is) this flaw allows an off-path attacker to
