Apple iOS 8.1.2 IOSurface code injection

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.

A vulnerability classified as critical has been found in Apple iOS 8.1.2 (Smartphone Operating System). This affects some unknown processing of the component IOSurface. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

IOSurface in Apple iOS before 8.2, Apple OS X through 10.10.2, and Apple TV before 7.1 allows attackers to execute arbitrary code in a privileged context via a crafted app that leverages "type confusion" during serialized-object handling.

The weakness was shared 03/09/2015 by Ian Beer with Google Project Zero as HT204423 as confirmed advisory (Website). The advisory is shared at This vulnerability is uniquely identified as CVE-2015-1061 since 01/16/2015. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 04/15/2022). It is expected to see the exploit prices for this product increasing in the near future.MITRE ATT&CK project uses the attack technique T1059 for this issue.
