CVE-2002-0511 describes a vulnerability in the default configuration of the Name Service Cache Daemon (nscd) in Caldera OpenLinux versions 3.1 and 3.1.1. This flaw allows nscd to use cached PTR records instead of querying the authoritative DNS server for A records, potentially enabling remote attackers to bypass hostname-based access restrictions. With a CVSS score of 7.5, this vulnerability is considered high severity, indicating a network-based attack with low complexity that could lead to partial compromise of confidentiality, integrity, and availability. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
