Descriptions

A vulnerability stemming from failure to properly clean up closed OMAPI connections can lead to exhaustion of the pool of socket descriptors available to the DHCP server. Affects ISC DHCP 4.1.0 to 4.1-ESV-R15, 4.2.0 to 4.2.8, 4.3.0 to 4.3.6. Older versions may also be affected but are well beyond their end-of-life (EOL). Releases prior to 4.1.0 have not been tested.

Una vulnerabilidad derivada del error al limpiar correctamente las conexiones OMAPI cerradas puede conducir al agotamiento del grupo de descriptores del socket disponibles para el servidor DHCP. Afecta a ISC DHCP desde la versión 4.1.0 hasta la 4.1-ESV-R15, desde la versión 4.2.0 hasta la 4.2.8 y desde la versión 4.3.0 hasta la 4.3.6. Las versiones anteriores podrían hacerse visto afectadas, pero han sobrepasado por mucho su fin de vida útil. Las versiones anteriores a la 4.1.0 no han sido probadas.

It was found that the DHCP daemon did not properly clean up closed OMAPI connections in certain cases. A remote attacker able to connect to the OMAPI port could use this flaw to exhaust file descriptors in the DHCP daemon, leading to a denial of service in the OMAPI functionality.
