Apple Mac OS X 10.9.2 Kernel information disclosure

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability has been found in Apple Mac OS X 10.9.2 (Operating System) and classified as problematic. This vulnerability affects some unknown functionality of the component Kernel. The manipulation with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

The kernel in Apple OS X through 10.9.2 places a kernel pointer into an XNU object data structure accessible from user space, which makes it easier for local users to bypass the ASLR protection mechanism by reading an unspecified attribute of the object.

The weakness was released 04/22/2014 by Ian Beer with Google Project Zero as HT6207 as confirmed advisory (Website). The advisory is shared for download at support.apple.com. The public release was coordinated with the vendor. This vulnerability was named CVE-2014-1322 since 01/08/2014. The exploitation appears to be difficult. The attack needs to be approached locally. No form of authentication is required for a successful exploitation. Technical details are unknown but a public exploit is available. The MITRE ATT&CK project declares the attack technique as T1592. The advisory points out:

A local user can read kernel pointers, which can be used to bypass kernel address space layout randomization

A public exploit has been developed in ANSI C. It is possible to download the exploit at securityfocus.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 73648 (Mac OS X Multiple Vulnerabilities (Security Update 2014-002)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 122028 (Apple Mac OS X Security Update 2014-002 Not Installed (HT6207)).

Applying the patch Security Update 2014-002 is able to eliminate this problem. The bugfix is ready for download at support.apple.com. A possible mitigation has been published immediately after the disclosure of the vulnerability. The advisory contains the following remark:

This issue was addressed through removing the pointers from the object.

The vulnerability is also documented in the databases at X-Force (92701), Exploit-DB (39147), Tenable (73648), SecurityFocus (BID 67023†) and SecurityTracker (ID 1030133†).
