Security readout for executives and security teams
CVE-2001-0735 is an old local-code-execution flaw in cfingerd, a finger daemon. If cfingerd 1.4.3 or earlier is installed with ALLOW_LINE_PARSING enabled, a local user can trigger a buffer overflow through a specially long .nofinger line. Business urgency depends on whether this legacy service is still present on multi-user systems. Exposure is most plausible on legacy Unix/Linux hosts running cfingerd 1.4.3 or earlier, especially systems allowing local shell users. Modern environments are unlikely to be exposed unless the finger service was intentionally retained or inherited. Treat this as a targeted legacy cleanup item, not a broad emergency. Prioritize quickly if cfingerd exists on shared systems with local users, because successful exploitation could execute code locally and potentially support privilege escalation depending on deployment. Mitigation focus: Inventory hosts for cfingerd and remove it where the finger service is unnecessary.; Check vendor guidance, including Debian DSA-066, for supported update or package replacement paths.; Disable ALLOW_LINE_PARSING where configuration or build controls permit it..
