Title: ISC DHCP Server Host Definition Remote Denial Of Service Vulnerability
Severity: MODERATE
Description:
ISC DHCP is a reference implementation of the DHCP protocol, including a DHCP server, client, and relay agent.
ISC DHCP Server is prone to a remote denial-of-service vulnerability because it fails to adequately handle specially crafted DHCP requests. This issue occurs when the server configuration mixes host definitions by using both 'dhcp-client-identifier' and 'hardware ethernet' directives.
Attackers can exploit this issue to cause the server to terminate, thus denying service to legitimate users.
