CyberRota Analysis
AI-GeneratedA vulnerability exists in the dhcp-server that allows remote attackers with network access to the OMAPI port to exploit a buffer overflow via a specially crafted lease creation request. This can lead to a persistent denial of service (DoS), causing the `dhcpd` service to crash and necessitating manual intervention for recovery. Organizations using dhcp-server, particularly those without TSIG authentication, should prioritize addressing this issue to mitigate potential service disruptions.

Original NVD Description
A flaw was found in dhcp-server. A remote attacker with network access to the OMAPI (Open Management Application Programming Interface) port, especially if not secured with TSIG (Transaction Signature) key authentication, could send a specially crafted lease creation request. This request, containing an overly long InfiniBand MAC address, triggers a buffer overflow in the `print_hw_addr()` function. Successful exploitation leads to a persistent denial of service (DoS), causing the `dhcpd` service to crash and preventing it from restarting without manual intervention.
