CVE-2014-4495
First published: Fri Jan 30 2015(Updated: )
The kernel in Apple iOS before 8.1.3, Apple OS X before 10.10.2, and Apple TV before 7.0.3 does not enforce the read-only attribute of a shared memory segment during use of a custom cache mode, which allows attackers to bypass intended access restrictions via a crafted app.
