| 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. | |||||

| 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. | |||||
| CVE-2017-14491 | 13 Arista, Arubanetworks, Canonical and 10 more | 29 Eos, Arubaos, Ubuntu Linux and 26 more | 2023-11-07 | 7.5 HIGH | 9.8 CRITICAL |
| 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. | |||||
| CVE-2017-13704 | 6 Canonical, Debian, Fedoraproject and 3 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| In dnsmasq before 2.78, if the DNS packet size does not match the expected size, the size parameter in a memset call gets a negative value. As it is an unsigned value, memset ends up writing up to 0xffffffff zero's (0xffffffffffffffff in 64 bit platforms), making dnsmasq crash. | |||||
| CVE-2015-8899 | 2 Canonical, Thekelleys | 2 Ubuntu Linux, Dnsmasq | 2023-11-07 | 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 | 2023-11-07 | 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 | 2023-11-07 | 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-2022-0934 | 2 Redhat, Thekelleys | 2 Enterprise Linux, Dnsmasq | 2023-03-07 | 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-2019-14513 | 2 Debian, Thekelleys | 2 Debian Linux, Dnsmasq | 2023-03-03 | 5.0 MEDIUM | 7.5 HIGH |
| Improper bounds checking in Dnsmasq before 2.76 allows an attacker controlled DNS server to send large DNS packets that result in a read operation beyond the buffer allocated for the packet, a different vulnerability than CVE-2017-14491. | |||||
| CVE-2012-3411 | 2 Redhat, Thekelleys | 4 Enterprise Linux Desktop, Enterprise Linux Server, Enterprise Linux Workstation and 1 more | 2023-02-13 | 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-2019-14834 | 2 Fedoraproject, Thekelleys | 2 Fedora, Dnsmasq | 2023-02-12 | 4.3 MEDIUM | 3.7 LOW |
| 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. | |||||
| CVE-2017-15107 | 1 Thekelleys | 1 Dnsmasq | 2019-10-09 | 5.0 MEDIUM | 7.5 HIGH |
| A vulnerability was found in the implementation of DNSSEC in Dnsmasq up to and including 2.78. Wildcard synthesized NSEC records could be improperly interpreted to prove the non-existence of hostnames that actually exist. | |||||
| CVE-2009-2958 | 1 Thekelleys | 1 Dnsmasq | 2017-09-19 | 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. | |||||
| CVE-2009-2957 | 1 Thekelleys | 1 Dnsmasq | 2017-09-19 | 6.8 MEDIUM | N/A |
| 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 | 2017-08-08 | 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. | |||||
