CVE-2013-0977: dyld in Apple iOS before 6.1.3 and Apple TV before 5.2.1 does not properly manage the state of file loading...

dyld in Apple iOS before 6.1.3 and Apple TV before 5.2.1 does not properly manage the state of file loading for Mach-O executable files, which allows local users to bypass intended code-signing requirements via a file that contains overlapping segments.

Security readout for executives and security teams

This is an Apple code-signing bypass affecting older iOS and Apple TV releases. A local user could use a specially structured Mach-O file to bypass intended code-signing checks. It matters mainly where legacy devices remain in use, because vendor advisories identify fixed versions from March 2013. Exposure is limited to Apple iOS versions before 6.1.3 and Apple TV versions before 5.2.1. Modern, patched, or retired devices should not be affected based on the provided sources. Treat this as a legacy exposure cleanup item unless old Apple devices remain operational. It is not supported by the provided evidence as actively exploited, but code-signing bypasses weaken platform trust and should not persist in production fleets. Mitigation focus: Update iOS devices to 6.1.3 or later where supported.; Update Apple TV devices to 5.2.1 or later where supported.; Inventory legacy Apple devices still running older firmware..
