| 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-2017-14495 | Hig | 7.5 | < 2.78-18.3.1 | 2.78-18.3.1 | Oct 3, 2017 | Memory leak in dnsmasq before 2.78, when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service (memory consumption) via vectors involving DNS response creation. | |
| CVE-2017-14494 | Med | 5.9 | < 2.78-18.3.1 | 2.78-18.3.1 | Oct 3, 2017 | dnsmasq before 2.78, when configured as a relay, allows remote attackers to obtain sensitive memory information via vectors involving handling DHCPv6 forwarded requests. | |
| CVE-2017-14493 | Cri | 9.8 | < 2.78-18.3.1 | 2.78-18.3.1 | Oct 3, 2017 | Stack-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DHCPv6 request. | |
| CVE-2017-14492 | Cri | 9.8 | < 2.78-18.3.1 | 2.78-18.3.1 | Oct 3, 2017 | Heap-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted IPv6 router advertisement request. |
