CVE-2007-5365

71
FAUCET Score

CVE-2007-5365 describes a stack-based buffer overflow in the cons_options function of dhcpd, affecting OpenBSD 4.0 through 4.2 and other ISC dhcp-2 based implementations, including Debian, Red Hat, Sun, and Ubuntu. This vulnerability, with a CVSS score of 7.2, allows remote attackers to achieve arbitrary code execution or a denial of service by sending a crafted DHCP request with a small maximum message size. While not actively exploited in the wild (KEV: No) and lacking Metasploit or Nuclei modules, an ExploitDB entry exists for a denial-of-service exploit, though there is minimal community discussion or media coverage.
