Buffer overflow in efingerd 1.5 and earlier, and possibly up to 1.61, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a finger request from an IP address with a long hostname that is obtained via a reverse DNS lookup.

Security readout for executives and security teams

CVE-2002-0423 is an old remote buffer overflow in efingerd, a finger daemon. A remote request can trigger unsafe handling of an unusually long hostname obtained through reverse DNS, causing service failure and possibly code execution. Exposure matters only where this legacy service is still installed and reachable. Likely exposure is limited to legacy systems running efingerd or packaged derivatives with the finger service reachable over the network. Modern environments are usually unaffected unless old Unix/Linux hosts, appliances, or forgotten services still run efingerd. Prioritize remediation if any internet-facing or broadly reachable efingerd instance exists. If no efingerd or finger service is present, business urgency is low. The main risk is a forgotten legacy service creating avoidable remote denial-of-service or code-execution exposure. Mitigation focus: Identify and disable efingerd where business use is absent.; Restrict finger service exposure to trusted networks only.; Check maintainer or distribution guidance for fixed or removed packages..
