Medium Nessus Plugin ID 22159
The remote DHCP server is affected by a denial of service vulnerability.
The ISC DHCP server running on the remote host is affected by a denial of service vulnerability in the supersede_lease() function within file memory.c due to improper handling of DHCPDISCOVER packets that have a client-identifier option that is exactly 32 bytes long. An unauthenticated, remote attacker can exploit this to cause the server to exit unexpectedly.
