dnsmasq: loose query name check in reply_query() makes forging replies easier for an off-path attacker

A flaw was found in dnsmasq. When getting a reply from a forwarded query, dnsmasq checks in forward.c:replyquery, 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...

DNS Cache Poisoning

apport is vulnerable to DNS cache poisoning. When getting a reply from a forwarded query, dnsmasq checks in forward.c:replyquery if the reply destination address/port is one of those used by the pending forwarded queries. However, it does not use the address/port to retrieve the exact forwarded...

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 find several different domains all having the same hash substantially reducing the number of attempts they would have to perform to forge a reply and get it accepted by dnsmasq. This is in contrast with RFC5452 which specifies that the query name is one of the attributes of a query that must be used to match a reply. This flaw could be abused to perform a DNS Cache Poisoning attack. If chained with CVE-2020-25684 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. 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.
