Apple Mac OS X up to 10.9.3 memory corruption

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 was found in Apple Mac OS X up to 10.9.3 (Operating System). It has been classified as critical. This affects an unknown function. 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:

Heap-based buffer overflow in the kernel in Apple OS X before 10.10 allows physically proximate attackers to execute arbitrary code via crafted resource forks in an HFS filesystem.

The weakness was shared 10/16/2014 by Maksymilian Arciemowicz as HT6535 as confirmed advisory (Website). It is possible to read the advisory at support.apple.com. This vulnerability is uniquely identified as CVE-2014-4433 since 06/20/2014. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available. The advisory points out:

A heap-based buffer overflow issue existed in the handling of HFS resource forks. A maliciously crafted filesystem may cause an unexpected system shutdown or arbitrary code execution with kernel privileges.

A public exploit has been developed by Maksymilian Arciemowicz and been published 2 years after the advisory. 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 $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 78550 (Mac OS X < 10.10 Multiple Vulnerabilities (POODLE) (Shellshock)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks.

Upgrading to version 10.10 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability. The advisory contains the following remark:

The issue was addressed through improved bounds checking.

The vulnerability is also documented in the databases at X-Force (97634), Exploit-DB (38917), Tenable (78550), SecurityFocus (BID 70620†) and SecurityTracker (ID 1031063†). The entries VDB-10344, VDB-67593, VDB-67592 and VDB-67590 are related to this item. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
