Attack-Flow Graph

Executive Summary

This is a vulnerability in Oracle Solaris 11.4's Filesystems component. It allows a low-privileged attacker with local access to cause a denial of service (DOS) by crashing or hanging the system repeatedly.

Detection Guidance

Detection of this vulnerability requires checking for Oracle Solaris 11.4 systems and monitoring for filesystem-related crashes or hangs. Review system logs for repeated crashes or hangs, particularly after filesystem operations. Use commands like 'uname -a' to verify Solaris version and 'svcs -a' to check for failed services. Monitor '/var/adm/messages' for filesystem errors.

Impact Analysis

If exploited, it could disrupt Oracle Solaris operations, leading to system crashes or hangs. This may cause downtime, data unavailability, and operational disruptions for systems running the affected version.

Compliance Impact

This vulnerability causes denial-of-service (DoS) conditions in Oracle Solaris, leading to system crashes or hangs. Such disruptions may impact availability of critical systems, which could affect compliance with regulations like GDPR (data processing availability) or HIPAA (system reliability for protected health information).

Mitigation Strategies

Apply the latest Oracle Solaris patches from Oracle to address the vulnerability in the Filesystems component. Monitor Oracle's security advisories for updates and restrict user access to minimize attack surface.
