dnsmasq: multiple queries forwarded for the same name makes forging replies easier for an off-path attacker

A flaw was found in dnsmasq. 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...

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...

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...
