2024-02-14 CVE-2023-50387 Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records. Fedora, Bind, Windows_server_2008, Windows_server_2012, Windows_server_2016, Windows_server_2019, Windows_server_2022, Windows_server_2022_23h2, Knot_resolver, Unbound, Recursor, Enterprise_linux, Dnsmasq 7.5
2024-06-06 CVE-2023-49441 dnsmasq 2.9 is vulnerable to Integer Overflow via forward_query. Dnsmasq 7.5
2023-03-15 CVE-2023-28450 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. Dnsmasq 7.5
2017-10-04 CVE-2017-14491 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 DNS response. Eos, Arubaos, Ubuntu_linux, Debian_linux, Honor_v9_play_firmware, Geforce_experience, Linux_for_tegra, Leap, Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation, Ruggedcom_rm1224_firmware, Scalance_m\-800_firmware, Scalance_s615_firmware, Scalance_w1750d_firmware, Linux_enterprise_debuginfo, Linux_enterprise_point_of_sale, Linux_enterprise_server, Diskstation_manager, Router_manager, Dnsmasq 9.8
2021-01-20 CVE-2020-25683 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. A remote attacker, who can create valid DNS replies, could use this flaw to cause an overflow in a heap-allocated memory. This flaw is caused by the lack of length checks in rfc1035.c:extract_name(), which could be abused to make the code execute memcpy() with a negative size in get_rdata() and cause a crash in... Debian_linux, Fedora, Dnsmasq 5.9
2021-01-20 CVE-2020-25684 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... Eos, Debian_linux, Fedora, Dnsmasq 3.7
2021-01-20 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: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... Eos, Debian_linux, Fedora, Dnsmasq 3.7
2021-01-20 CVE-2020-25681 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 cause a buffer overflow with arbitrary data in a heap memory segment, possibly executing code on the machine. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Debian_linux, Fedora, Dnsmasq 8.1
