2022-08-29 CVE-2022-0934 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. Enterprise_linux, Dnsmasq 7.5
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
