Detailsinfo

A vulnerability classified as critical was found in Apple Mac OS X 10.10/10.10.1 (Operating System). Affected by this vulnerability is an unknown part of the component Bluetooth. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The Bluetooth driver in Apple OS X before 10.10.2 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (arbitrary-size bzero of kernel memory) via a crafted app.

The weakness was shared 01/27/2015 by Ian Beer (PanguTeam) with Google Project Zero as HT204244 as confirmed advisory (Website). The advisory is shared at support.apple.com. This vulnerability is known as CVE-2014-8836 since 11/14/2014. The attack needs to be done within the local network. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available. The advisory points out:

An error existed in the Bluetooth driver that allowed a malicious application to control the size of a write to kernel memory. The issue was addressed through additional input validation.

It is possible to download the exploit at packetstormsecurity.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k.
