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.

Security readout for executives and security teams

This old flaw affects Caldera OpenLinux systems using the default nscd configuration. Cached reverse-DNS data could be trusted in a way that helps bypass applications that make access decisions from host names. The sources do not provide a severity score or evidence of active exploitation. Exposure appears limited to legacy Caldera OpenLinux 3.1 and 3.1.1 deployments running the default Name Service Cache Daemon configuration, especially where applications trust DNS host names for access control. Modern environments are unlikely to be exposed unless they retain these obsolete systems. Prioritize this only if the organization still operates Caldera OpenLinux 3.1 or 3.1.1, or inherited systems using hostname-based trust. For most modern environments, urgency is low pending asset confirmation, but unmanaged legacy infrastructure should be reviewed. Mitigation focus: Check the Caldera CSSA-2002-013.0 advisory for vendor-approved guidance.; Inventory legacy Caldera OpenLinux 3.1 and 3.1.1 systems.; Identify applications relying on hostname-based access restrictions..
