CVE-2004-0460
Buffer overflow in the logging capability for the DHCP daemon (DHCPD)
for ISC DHCP 3.0.1rc12 and 3.0.1rc13 allows remote attackers to cause
a denial of service (server crash) and possibly execute arbitrary code
via multiple hostname options in (1) DISCOVER, (2) OFFER, (3) REQUEST,
(4) ACK, or (5) NAK messages, which can generate a long string when
writing to a log file.");
