Apple Mac OS X up to 10.10.3 HFS Parameter Kernel Memory 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, which was classified as problematic, was found in Apple Mac OS X 10.9.5/10.10/10.10.1/10.10.2/10.10.3 (Operating System). Affected is an unknown functionality of the component HFS Parameter Handler. The manipulation with an unknown input leads to a information disclosure vulnerability (Kernel Memory). CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes:

The kernel in Apple iOS before 8.4 and OS X before 10.10.4 does not properly handle HFS parameters, which allows attackers to obtain sensitive memory-layout information via a crafted app.

The weakness was shared 06/30/2015 by Peter Rutenbar with Zero Day Initiative as HT204942 as confirmed advisory (Website). The advisory is shared for download at support.apple.com. The vendor cooperated in the coordination of the public release. This vulnerability is traded as CVE-2015-3721 since 05/07/2015. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1592.

The vulnerability scanner Nessus provides a plugin with the ID 84488 (Mac OS X 10.10.x < 10.10.4 Multiple Vulnerabilities (GHOST) (Logjam)), 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 123680 (Apple Mac OS X v10.10.4 and Security Update 2015-005 Not Installed (APPLE-SA-2015-06-30-2)).

Upgrading to version 10.10.4 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (104211), Tenable (84488), SecurityFocus (BID 75491†), SecurityTracker (ID 1032760†) and Vulnerability Center (SBV-50902†). The entries VDB-75568, VDB-76185, VDB-76186 and VDB-76187 are related to this item. VulDB is the best source for vulnerability data and more expert information about this specific topic.
