Denial of service in Kea DHCP daemons (versions 2.6.0-2.6.4 and 3.0.0-3.0.2) allows unauthenticated remote attackers to crash affected services by sending maliciously crafted messages to API sockets or HA listeners, triggering a stack overflow. Vulnerable Kea installations across Ubuntu, Red Hat, SUSE, and Debian are susceptible to service interruption attacks with no authentication required. A patch is available for affected distributions.
A missing check on incoming client requests can be exploited to cause a situation where the Kea server's lease storage contains leases which are rejected as invalid when the server tries to load. Rated medium severity (CVSS 6.5), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
An invalid hostname option can trigger an assertion failure in the Kea DHCPv4 server process (kea-dhcp4), causing the server process to exit. Rated medium severity (CVSS 6.5), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
A packet containing a malformed DUID can cause the Kea DHCPv6 server process (kea-dhcp6) to exit due to an assertion failure. Rated medium severity (CVSS 6.5), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
The kea-dhcp4 and kea-dhcp6 servers 0.9.2 and 1.0.0-beta in ISC Kea, when certain debugging settings are used, allow remote attackers to cause a denial of service (daemon crash) via a malformed. Rated medium severity (CVSS 6.8), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.
