CVE-2013-0198 1 Thekelleys 1 Dnsmasq 2025-04-11 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-2009-2958 2 Redhat, Thekelleys 2 Enterprise Linux, Dnsmasq 2025-04-09 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-2008-3214 1 Thekelleys 1 Dnsmasq 2025-04-09 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.
CVE-2009-2957 2 Redhat, Thekelleys 2 Enterprise Linux, Dnsmasq 2025-04-09 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-2005-0877 1 Thekelleys 1 Dnsmasq 2025-04-03 7.5 High
Dnsmasq before 2.21 allows remote attackers to poison the DNS cache via answers to queries that were not made by Dnsmasq.
CVE-2023-49441 1 Thekelleys 1 Dnsmasq 2025-03-14 7.5 High
dnsmasq 2.9 is vulnerable to Integer Overflow via forward_query.
CVE-2021-45957 1 Thekelleys 1 Dnsmasq 2024-11-21 9.8 Critical
Dnsmasq 2.86 has a heap-based buffer overflow in answer_request (called from FuzzAnswerTheRequest and fuzz_rfc1035.c). 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-2021-45956 1 Thekelleys 1 Dnsmasq 2024-11-21 9.8 Critical
Dnsmasq 2.86 has a heap-based buffer overflow in print_mac (called from log_packet and dhcp_reply). 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-2021-45955 1 Thekelleys 1 Dnsmasq 2024-11-21 9.8 Critical
Dnsmasq 2.86 has a heap-based buffer overflow in resize_packet (called from FuzzResizePacket and fuzz_rfc1035.c) because of the lack of a proper bounds check upon pseudo header re-insertion. 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." However, a contributor states that a security patch (mentioned in 016162.html) is needed
CVE-2021-45954 1 Thekelleys 1 Dnsmasq 2024-11-21 9.8 Critical
Dnsmasq 2.86 has a heap-based buffer overflow in extract_name (called from answer_auth and FuzzAuth). 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-2021-45953 1 Thekelleys 1 Dnsmasq 2024-11-21 9.8 Critical
Dnsmasq 2.86 has a heap-based buffer overflow in extract_name (called from hash_questions and fuzz_util.c). 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-2021-45952 1 Thekelleys 1 Dnsmasq 2024-11-21 9.8 Critical
Dnsmasq 2.86 has a heap-based buffer overflow in dhcp_reply (called from dhcp_packet and FuzzDhcp). 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-2021-45951 1 Thekelleys 1 Dnsmasq 2024-11-21 9.8 Critical
Dnsmasq 2.86 has a heap-based buffer overflow in check_bad_address (called from check_for_bogus_wildcard and FuzzCheckForBogusWildcard). 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-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 2024-11-21 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.
CVE-2019-14834 3 Fedoraproject, Redhat, Thekelleys 3 Fedora, Enterprise Linux, Dnsmasq 2024-11-21 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-2019-14513 3 Debian, Redhat, Thekelleys 3 Debian Linux, Enterprise Linux, Dnsmasq 2024-11-21 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-2017-15107 1 Thekelleys 1 Dnsmasq 2024-11-21 N/A
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.
