Security readout for executives and security teams
CVE-2015-3797 is an Apple libc regular-expression parsing flaw. On affected iOS and OS X versions, a crafted regular expression could corrupt memory, crash an application, or potentially execute code. Business risk is mainly legacy Apple endpoints that never received the 2015 security updates. Exposure is most likely limited to obsolete Apple devices running iOS earlier than 8.4.1 or OS X earlier than 10.10.5, especially where applications process attacker-influenced regular expressions through libc TRE. Modern supported Apple platforms are not identified as affected in the supplied sources. Treat this as a legacy-system cleanup item unless vulnerable Apple versions remain in production. Prioritize remediation for internet-facing, kiosk, shared, or unmanaged devices because the impact includes application crash and possible code execution. Mitigation focus: Upgrade affected iOS devices to 8.4.1 or later where supported.; Upgrade affected OS X systems to 10.10.5 or later where supported.; Retire or isolate devices that cannot receive Apple security updates..
