CVE-2004-1006
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedFormat string vulnerability in the log functions in dhcpd for dhcp 2.x allows remote DNS servers to execute arbitrary code via certain DNS messages, a different vulnerability than CVE-2002-0702.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopeddhcp 3.x stable release (post 3.0.1, e.g., 3.1.x or later stable branch) - consult vendor for distribution-specific patched version
- 1. Identify the currently installed DHCP server version using 'dhcpd -v' or package manager commands
- 2. Consult vendor security advisories for your distribution (Debian DSA-584 referenced) to obtain the patched version
- 3. For Debian systems, apply the update via 'apt-get update && apt-get install dhcp3-server' or equivalent
- 4. Restart the dhcpd service after patching using 'service dhcpd restart' or equivalent
- 5. Verify the new version is running and check system logs for any startup errors
- 6. Review /var/log/messages or equivalent for successful daemon operation
