Stack-based buffer overflow in the openSharedCacheFile function in dyld.cpp in dyld in Apple iOS 5.1.x and 6.x through 6.1.3 makes it easier for attackers to conduct untethering attacks via a long string in the DYLD_SHARED_CACHE_DIR environment variable.

Security readout for executives and security teams

CVE-2013-3950 is an old Apple iOS dyld memory-safety flaw. A specially long DYLD_SHARED_CACHE_DIR environment variable could trigger a stack buffer overflow and support untethering attacks. The main business concern is unmanaged legacy iOS 5.1.x or 6.x devices, not modern supported iOS fleets. Exposure is likely limited to obsolete Apple iOS 5.1.x and 6.x through 6.1.3 devices. Typical enterprise exposure depends on whether legacy iPhones, iPads, lab devices, kiosks, or jailbroken devices remain in use. Treat as a legacy-device hygiene issue unless affected devices support business operations. There is no source-backed evidence of active exploitation, but unsupported mobile endpoints can create avoidable operational and compliance risk. Mitigation focus: Inventory for iOS 5.1.x and 6.x through 6.1.3 devices.; Retire or isolate obsolete iOS devices that cannot run supported software.; Review Apple advisory HT5934 and listed security announcements for vendor guidance..
