CVE-2014-4455
dyld in Apple iOS before 8.1.1 and Apple TV before 7.0.2 does not properly handle overlapping segments in Mach-O executable files, which allows local users to bypass intended code-signing restrictions via a crafted file.
Does this matter?
Lower severity and a low EPSS score (0.39%). Track it; it rarely justifies an emergency change on its own.
