CVE-2002-0511: Nscd

High severity, CVSS 7.5. EPSS: 1.6% chance of exploitation in the next 30 days.

The default configuration of Name Service Cache Daemon (nscd) in Caldera OpenLinux 3.1 and 3.1.1 uses cached PTR records instead of consulting the authoritative DNS server for the A record, which could make it easier for remote attackers to bypass applications that restrict access based on host names.
