Security readout for executives and security teams

This is an old Mac OS X login issue affecting version 10.4.2 and earlier when Fast User Switching is enabled. An attacker who already knows passwords for at least two accounts may be able to access other accounts. The record does not show active exploitation. Exposure is most plausible on obsolete Mac OS X 10.4.2 or earlier systems with multiple local accounts and Fast User Switching enabled. Modern macOS exposure is not stated in the sources. Treat as a legacy-system hygiene issue. It is not supported as actively exploited, but shared or unmanaged old Macs could expose user accounts and should be updated, isolated, or retired. Mitigation focus: Inventory any Mac OS X 10.4.2 or earlier systems.; Review Apple advisories APPLE-SA-2005-08-15 and APPLE-SA-2005-08-17.; Apply applicable Apple security updates or vendor guidance..
