| CVE-2015-8899 | 2 Canonical, Thekelleys | 2 Ubuntu Linux, Dnsmasq | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Dnsmasq before 2.76 allows remote servers to cause a denial of service (crash) via a reply with an empty DNS address that has an (1) A or (2) AAAA record defined locally. | |||||
| CVE-2015-3294 | 2 Oracle, Thekelleys | 2 Solaris, Dnsmasq | 2024-11-21 | 6.4 MEDIUM | N/A |
| The tcp_request function in Dnsmasq before 2.73rc4 does not properly handle the return value of the setup_reply function, which allows remote attackers to read process memory and cause a denial of service (out-of-bounds read and crash) via a malformed DNS request. | |||||
| CVE-2013-0198 | 1 Thekelleys | 1 Dnsmasq | 2024-11-21 | 5.0 MEDIUM | N/A |
| Dnsmasq before 2.66test2, when used with certain libvirt configurations, replies to queries from prohibited interfaces, which allows remote attackers to cause a denial of service (traffic amplification) via spoofed TCP based DNS queries. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-3411. | |||||
| CVE-2012-3411 | 2 Redhat, Thekelleys | 4 Enterprise Linux Desktop, Enterprise Linux Server, Enterprise Linux Workstation and 1 more | 2024-11-21 | 5.0 MEDIUM | N/A |
| Dnsmasq before 2.63test1, when used with certain libvirt configurations, replies to requests from prohibited interfaces, which allows remote attackers to cause a denial of service (traffic amplification) via a spoofed DNS query. | |||||
| CVE-2009-2958 | 1 Thekelleys | 1 Dnsmasq | 2024-11-21 | 4.3 MEDIUM | N/A |
| The tftp_request function in tftp.c in dnsmasq before 2.50, when --enable-tftp is used, allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a TFTP read (aka RRQ) request with a malformed blksize option. | |||||

| Heap-based buffer overflow in the tftp_request function in tftp.c in dnsmasq before 2.50, when --enable-tftp is used, might allow remote attackers to execute arbitrary code via a long filename in a TFTP packet, as demonstrated by a read (aka RRQ) request. | |||||
| CVE-2008-3214 | 1 Thekelleys | 1 Dnsmasq | 2024-11-21 | 7.8 HIGH | N/A |
| dnsmasq 2.25 allows remote attackers to cause a denial of service (daemon crash) by (1) renewing a nonexistent lease or (2) sending a DHCPREQUEST for an IP address that is not in the same network, related to the DHCP NAK response from the daemon. | |||||

NOTE: the vendor's position is that CVE-2021-45951 through CVE-2021-45957 "do not represent real vulnerabilities, to the best of our knowledge." | |||||
| CVE-2023-50387 | 8 Fedoraproject, Isc, Microsoft and 5 more | 13 Fedora, Bind, Windows Server 2008 and 10 more | 2024-06-10 | N/A | 7.5 HIGH |
| 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. | |||||
| CVE-2023-28450 | 1 Thekelleys | 1 Dnsmasq | 2024-02-04 | N/A | 7.5 HIGH |
| 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 Redhat, Thekelleys | 2 Enterprise Linux, Dnsmasq | 2024-02-04 | N/A | 7.5 HIGH |
| 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 | 4 Fedoraproject, Oracle, Redhat and 1 more | 4 Fedora, Communications Cloud Native Core Network Function Cloud Native Environment, Enterprise Linux and 1 more | 2024-02-04 | 4.3 MEDIUM | 4.0 MEDIUM |
| 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 random transmission ID to forge a reply and get it accepted by dnsmasq. This flaw makes a DNS Cache Poisoning attack much easier. The highest threat from this vulnerability is to data integrity. | |||||
