Security readout for executives and security teams

This is an old WebKit memory-corruption issue in Apple software. A user visiting a malicious website could allow an attacker to run code in the browser context or crash the app. The affected line is iOS before 10.2.1, Safari before 10.0.3, iCloud before 6.1.1, and iTunes before 12.5.5. Exposure is most likely on legacy Apple endpoints or managed images still running iOS, Safari, iCloud for Windows, or iTunes below the fixed versions named in the CVE description. Prioritize remediation for any remaining legacy Apple systems because the issue allows remote code execution through web browsing. Modern, fully updated fleets should have low residual exposure. Mitigation focus: Upgrade iOS to 10.2.1 or later where applicable.; Upgrade Safari to 10.0.3 or later where applicable.; Upgrade iCloud to 6.1.1 or later where applicable..
