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 | 2024-08-07 | 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-2009-2958 | 2 Redhat, Thekelleys | 2 Enterprise Linux, Dnsmasq | 2024-08-07 | 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. | ||||

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-2013-0198 | 1 Thekelleys | 1 Dnsmasq | 2024-08-06 | 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.

CVE-2015-3294 | 2 Oracle, Thekelleys | 2 Solaris, Dnsmasq | 2024-08-06 | 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-2017-15107 | 1 Thekelleys | 1 Dnsmasq | 2024-08-05 | N/A |

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-2017-14495 | 5 Canonical, Debian, Novell and 2 more | 8 Ubuntu Linux, Debian Linux, Leap and 5 more | 2024-08-05 | N/A |
Memory leak in dnsmasq before 2.78, when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service (memory consumption) via vectors involving DNS response creation. | ||||
CVE-2017-14496 | 6 Canonical, Debian, Google and 3 more | 9 Ubuntu Linux, Debian Linux, Android and 6 more | 2024-08-05 | N/A |
Integer underflow in the add_pseudoheader function in dnsmasq before 2.78 , when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service via a crafted DNS request. | ||||
CVE-2017-14491 | 13 Arista, Arubanetworks, Canonical and 10 more | 35 Eos, Arubaos, Ubuntu Linux and 32 more | 2024-08-05 | 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-2017-14494 | 5 Canonical, Debian, Novell and 2 more | 9 Ubuntu Linux, Debian Linux, Leap and 6 more | 2024-08-05 | N/A |
dnsmasq before 2.78, when configured as a relay, allows remote attackers to obtain sensitive memory information via vectors involving handling DHCPv6 forwarded requests. | ||||
CVE-2017-14493 | 5 Canonical, Debian, Opensuse and 2 more | 9 Ubuntu Linux, Debian Linux, Leap and 6 more | 2024-08-05 | N/A |
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. | ||||
CVE-2017-13704 | 6 Canonical, Debian, Fedoraproject and 3 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2024-08-05 | N/A |
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-2019-14834 | 3 Fedoraproject, Redhat, Thekelleys | 3 Fedora, Enterprise Linux, Dnsmasq | 2024-08-05 | 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 | 2024-08-05 | 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-2020-25682 | 4 Debian, Fedoraproject, Redhat and 1 more | 5 Debian Linux, Fedora, Enterprise Linux and 2 more | 2024-08-04 | 8.1 High |
A flaw was found in dnsmasq before 2.83. A buffer overflow vulnerability was discovered in the way dnsmasq extract names from DNS packets before validating them with DNSSEC data. An attacker on the network, who can create valid DNS replies, could use this flaw to cause an overflow with arbitrary data in a heap-allocated memory, possibly executing code on the machine. The flaw is in the rfc1035.c:extract_name() function, which writes data to the memory pointed by name assuming MAXDNAME*2 bytes are available in the buffer. However, in some code execution paths, it is possible extract_name() gets passed an offset from the base buffer, thus reducing, in practice, the number of available bytes that can be written in the buffer. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | ||||
CVE-2020-25683 | 4 Debian, Fedoraproject, Redhat and 1 more | 5 Debian Linux, Fedora, Enterprise Linux and 2 more | 2024-08-04 | 5.9 Medium |
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 dnsmasq, resulting in a denial of service. The highest threat from this vulnerability is to system availability. |
