|---|---|---|---|---|---|---|---|
| CVE-2022-0934 | — | < 2.78-18.18.1 | 2.78-18.18.1 | Aug 29, 2022 | 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 | — | < 2.78-18.18.1 | 2.78-18.18.1 | Apr 8, 2021 | 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 ran | ||
| CVE-2020-25686 | — | < 2.78-18.15.1 | 2.78-18.15.1 | Jan 20, 2021 | A flaw was found in dnsmasq before version 2.83. When receiving a query, dnsmasq does not check for an existing pending request for the same name and forwards a new request. By default, a maximum of 150 pending queries can be sent to upstream servers, so there can be at most 150 | ||
| CVE-2020-25681 | — | < 2.78-18.15.1 | 2.78-18.15.1 | Jan 20, 2021 | A flaw was found in dnsmasq before version 2.83.
