CVE-2020-25685
A flaw was found in dnsmasq before version 2.83. 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 DNSSE...

CVE-2020-25685
CVE-2020-25685 affects dnsmasq up to version 2.83. The issue arises from how forward.c:reply_query() matches replies to forwarded queries: it uses a weak hash of the query name, allowing an off-path attacker to forge replies by exploiting hash collisions. This vulnerability enables DNS cache pois...

CVE-2020-25686: Improperly Implemented Security Check for Standard
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...

dnsmasq: loose address/port 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 the forward.c:replyquery 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...
