2021-04-08 CVE-2021-3448 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. Fedora, Communications_cloud_native_core_network_function_cloud_native_environment, Enterprise_linux, Dnsmasq 4.0
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
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
2019-08-01 CVE-2019-14513 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. Debian_linux, Dnsmasq 7.5
2013-03-05 CVE-2012-3411 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. Enterprise_linux_desktop, Enterprise_linux_server, Enterprise_linux_workstation, Dnsmasq N/A
2020-01-07 CVE-2019-14834 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. Fedora, Dnsmasq 3.7
2018-01-23 CVE-2017-15107 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. Dnsmasq 7.5
2009-09-02 CVE-2009-2958 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. Dnsmasq N/A
2009-09-02 CVE-2009-2957 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. Dnsmasq N/A
2008-07-18 CVE-2008-3214 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. Dnsmasq N/A
