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 attacker on the network would have to perform to forge a reply and get it accepted by dnsmasq. This issue contrasts with RFC5452 which specifies a query's attributes that all must be used to match a reply. This flaw allows an attacker to perform a DNS Cache Poisoning attack. If chained with CVE-2020-25685 or CVE-2020-25686 the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.

A flaw was found in dnsmasq before version 2.83. A heap-based buffer overflow was discovered in dnsmasq when DNSSEC is enabled and before it validates the received DNS entries. A remote attacker who can create valid DNS replies could use this flaw to cause an overflow in a heap-allocated memory. This flaw is caused by the lack of length checks in rfc1035.c:extract_name() which could be abused to make the code execute memcpy() with a negative size in get_rdata() and cause a crash in dnsmasq resulting in a denial of service. The highest threat from this vulnerability is to system availability.
