CVE-2004-0461
HighSummary
The DHCP daemon (DHCPD) for ISC DHCP 3.0.1rc12 and 3.0.1rc13, when compiled in environments that do not provide the vsnprintf function, uses C include files that define vsnprintf to use the less safe vsprintf function, which can lead to buffer overflow vulnerabilities that enable a denial of service (server crash) and possibly execute arbitrary code.
Risk Assessment
The risk includes the possibility of remotely causing a DHCP server crash and potentially executing arbitrary code, which could lead to network disruption and system compromise.
Recommendation
Immediately upgrade ISC DHCP to version 3.0.1rc14 or later, which includes a fix for this vulnerability. If an upgrade is not possible, compile DHCPD in an environment that provides the safe vsnprintf function.
