CVE-2012-3664: WebKit, as used in Apple Safari before 6.0, allows remote attackers to execute arbitrary code or cause a de...

Security readout for executives and security teams

A malicious website could crash or potentially take over old Safari browsers because WebKit mishandled memory. For organizations still running Safari before 6.0, this is a client-side compromise risk. Current urgency depends on whether such legacy Apple endpoints remain in use. Exposure is likely limited to legacy Apple systems running Safari before 6.0 or bundled WebKit components covered by Apple 2012 advisories. Modern managed fleets are unlikely to be affected, but unmanaged, lab, kiosk, or long-retained systems should be checked. Prioritize discovery over emergency response unless legacy Safari is still present. If found on business endpoints, remediation should be prompt because browsing to a malicious site could enable code execution. Mitigation focus: Upgrade Safari to 6.0 or later where supported.; Apply the relevant Apple security updates from the 2012 advisories.; Remove or isolate unsupported Apple systems that cannot receive fixes..
