Security researchers from SentinelOne have discovered a security vulnerability affecting the Apple System Integrity Protection (SIP) The SIP is a security mechanism implemented by Apple in the OS X El Capitan operating system for the protection of certain system processes, files and folders from being modified or tampered with by other processes. The vulnerability is a non-memory corruption bug that exists in every version of OS X and allows users to execute arbitrary code on any binary. The exploit is very stable because the SIP feature can be bypassed triggering the flaw without compromising the kernel. Vilaa said he wasnt aware of any malicious exploitation of the vulnerability to date.”]
