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.
Conclusion & alert: CVE-2004-0461 is rated High Risk (75.2/100): CVSS Critical severity, with high exploitation likelihood (EPSS 12.13%, 94th percentile). Core evidence: EPSS ranks this CVE among the most likely to be exploited in the near term. EPSS rose +2.39% over the last day, indicating growing attacker interest.
