Detailsinfo

A vulnerability was found in Apple MacOS X up to 10.10.2 (Operating System). It has been classified as critical. This affects an unknown functionality of the component Kernel. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The kernel in Apple iOS before 8.3, Apple OS X before 10.10.3, and Apple TV before 7.2 allows attackers to cause a denial of service (out-of-bounds memory access) or obtain sensitive memory-content information via a crafted app.

The weakness was presented 04/08/2015 by Maxime Villard with m00nbsd as HT204659 as confirmed advisory (Website). The advisory is shared at support.apple.com. This vulnerability is uniquely identified as CVE-2015-1100 since 01/16/2015. An attack has to be approached locally. The successful exploitation needs a authentication. Technical details are unknown but a public exploit is available.

The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 82712 (Apple TV < 7.2 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment.
