Security readout for executives and security teams

This was a local, physical-access issue affecting older Mac OS X systems when the RSS Visualizer screensaver was enabled. A person at the machine could bypass the screen lock and cause Safari to launch. The business risk is mainly unattended or shared Macs that relied on screen locking for protection. Likely exposure is limited to Mac OS X versions before 10.7.4 where the RSS Visualizer screensaver is enabled. Remote exposure is not indicated in the provided sources; physical proximity is required. Treat this as a targeted physical-access risk rather than an internet-scale emergency. Remediate any remaining legacy Macs, especially in shared or unattended locations, because screen locks are a key control for protecting active sessions and local data. Mitigation focus: Update affected Mac OS X systems to 10.7.4 or later.; Disable RSS Visualizer screensaver on unpatched systems.; Prioritize shared, unattended, kiosk, lab, and executive Macs..
