Security readout for executives and security teams
This CVE describes a denial-of-service issue in the Oracle 9i 9.0.1.1 TNS Listener. A remote attacker could consume CPU by sending one malformed TCP packet to port 1521, potentially disrupting database connectivity. Exposure is most likely where Oracle 9i 9.0.1.1 TNS Listener is reachable on TCP/1521, especially from untrusted networks. Evidence for other versions is not provided. Treat as a legacy database availability risk. Prioritize systems that support critical business applications or expose TCP/1521 beyond trusted network segments. Mitigation focus: Check Oracle guidance for Oracle 9i 9.0.1.1 TNS Listener remediation.; Restrict TCP/1521 access to required database clients and application hosts.; Remove internet exposure for affected listener services where possible..
