Executive Summary

This is a vulnerability in Oracle Solaris 11.4 where an unauthenticated attacker with local access can cause a denial of service (DOS) by crashing or hanging the system. The attack requires logon to the infrastructure but no further authentication. The impact is limited to availability, with no effect on confidentiality or integrity.

Detection Guidance

This vulnerability affects Oracle Solaris 11.4 and requires local logon to exploit. Detection may involve checking for unusual system hangs or crashes. Review system logs for repeated crashes or hangs in Oracle Solaris services. Use commands like 'svcs -x' to check service status and 'logadm' to review logs for anomalies.

Impact Analysis

If you use Oracle Solaris 11.4, an attacker with local access could disrupt system operations by causing repeated crashes or hangs. This leads to downtime and potential loss of service for users and applications relying on the system.

Compliance Impact

This vulnerability causes denial-of-service (DoS) conditions in Oracle Solaris, leading to system crashes or hangs. Such disruptions can impact data availability, potentially violating compliance requirements for GDPR (data availability) and HIPAA (system reliability for protected health information).
