CVE-2002-0511

High
Published: Translated: NVD NIST

Summary

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. This could make it easier for remote attackers to bypass applications that restrict access based on host names.

Risk Assessment

Attackers may exploit this vulnerability to bypass application security, potentially leading to unauthorized access to system resources.

Recommendation

It is recommended to configure nscd to always consult authoritative DNS servers for up-to-date A records.
