|---|---|---|---|---|---|---|---|
| CVE-2023-28450 | — | < 2.78-18.21.1 | 2.78-18.21.1 | Mar 15, 2023 | An issue was discovered in Dnsmasq before 2.90. The default maximum EDNS.0 UDP packet size was set to 4096 but should be 1232 because of DNS Flag Day 2020. | ||
| CVE-2022-0934 | — | < 2.78-18.18.1 | 2.78-18.18.1 | Aug 29, 2022 | A single-byte, non-arbitrary write/use-after-free flaw was found in dnsmasq. This flaw allows an attacker who sends a crafted packet processed by dnsmasq, potentially causing a denial of service. | ||
| CVE-2021-3448 | — | < 2.78-18.18.1 | 2.78-18.18.1 | Apr 8, 2021 | A flaw was found in dnsmasq in versions before 2.85. When configured to use a specific server for a given network interface, dnsmasq uses a fixed port while forwarding queries. An attacker on the network, able to find the outgoing port used by dnsmasq, only needs to guess the ran | ||
| CVE-2020-25686 | — | < 2.78-18.15.1 | 2.78-18.15.1 | Jan 20, 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 | ||
| CVE-2020-25681 | — | < 2.78-18.15.1 | 2.78-18.15.1 | Jan 20, 2021 | A flaw was found in dnsmasq before version 2.83. A heap-based buffer overflow was discovered in the way RRSets are sorted before validating with DNSSEC data. An attacker on the network, who can forge DNS replies such as that they are accepted as valid, could use this flaw to caus | ||
| CVE-2020-25687 | — | < 2.78-18.15.1 | 2.78-18.15.1 | Jan 20, 2021 | 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. This flaw allows a remote attacker, who can create valid DNS replies, to cause an overflow in a heap-al | ||
| CVE-2020-25682 | — | < 2.78-18.15.1 | 2.78-18.15.1 | Jan 20, 2021 | A flaw was found in dnsmasq before 2.83. A buffer overflow vulnerability was discovered in the way dnsmasq extract names from DNS packets before validating them with DNSSEC data. An attacker on the network, who can create valid DNS replies, could use this flaw to cause an overflo | ||

| CVE-2020-25684 | — | < 2.78-18.15.1 | 2.78-18.15.1 | Jan 20, 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 ex | ||
| CVE-2020-25685 | — | < 2.78-18.15.1 | 2.78-18.15.1 | Jan 20, 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 c | ||
| CVE-2019-14834 | — | < 2.78-18.12.1 | 2.78-18.12.1 | Jan 7, 2020 | A vulnerability was found in dnsmasq before version 2.81, where the memory leak allows remote attackers to cause a denial of service (memory consumption) via vectors involving DHCP response creation. |
