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 was found in Google Chrome 31.0.1650.57 (Web Browser). It has been classified as very critical. Affected is an unknown function of the component Array Indices Handler. 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. CVE summarizes:

The DehoistArrayIndex function in hydrogen-dehoist.cc (aka hydrogen.cc) in Google V8 before 3.22.24.7, as used in Google Chrome before 31.0.1650.63, allows remote attackers to cause a denial of service (out-of-bounds read) via JavaScript code that sets a variable to the value of an array element with a crafted index.

The weakness was disclosed 11/15/2013 by Jakob Kummerow (Cloudfuzzer) with Chromium Development Community as 319860 as not defined advisory (Website). The advisory is available at googlechromereleases.blogspot.com. The public release has been coordinated in cooperation with the vendor. This vulnerability is traded as CVE-2013-6640 since 11/05/2013. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 06/02/2021).
