Attack-Flow Graph

Executive Summary

This is a vulnerability in Oracle Solaris 11.4 affecting the Filesystems component. It allows a low-privileged attacker with local access to cause a denial of service (DOS) by hanging or crashing the system repeatedly. The attack requires logon to the infrastructure where Solaris runs.

Detection Guidance

This vulnerability affects Oracle Solaris 11.4 filesystem components. Detection requires checking for filesystem-related crashes or hangs on systems running Solaris 11.4. Monitor system logs for repeated crashes or hangs, particularly after filesystem operations. Check for Oracle Solaris 11.4 installations using commands like 'pkg list' or 'uname -a'. Ensure all Solaris 11.4 systems are updated with the latest patches from Oracle.

Impact Analysis

If you use Oracle Solaris 11.4, an attacker with local access could disrupt system availability by causing crashes or hangs. This could lead to downtime, loss of service, and operational disruptions for systems relying on Solaris.

Compliance Impact

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

Mitigation Strategies

Apply the latest Oracle Solaris patches from Oracle to address the vulnerability. Ensure all systems running Oracle Solaris 11.4 are updated immediately to prevent potential denial of service attacks.
