CVSS: 4.3EPSS: 0%CPEs: 10EXPL: 0CVE-2020-25684 – dnsmasq: loose address/port check in reply_query() makes forging replies easier for an off-path attacker
https://notcve.org/view.php?id=CVE-2020-25684
19 Jan 2021 — 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 attrib... • https://bugzilla.redhat.com/show_bug.cgi?id=1889686 • CWE-358: Improperly Implemented Security Check for Standard •

https://notcve.org/view.php?id=CVE-2020-25685
19 Jan 2021 — 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 an... • https://bugzilla.redhat.com/show_bug.cgi?id=1889688 • CWE-326: Inadequate Encryption Strength •

https://notcve.org/view.php?id=CVE-2020-25686
19 Jan 2021 — 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 substantially reduce the number of attempts that it would have to perform to forge a reply and have it accepted by dnsmasq.
