CVE-2018-6065 is a high-severity vulnerability affecting Google Chrome prior to version 65.0.3325.146. This vulnerability allows for integer overflow in computing the required allocation size when instantiating a new JavaScript object in the V8 engine. Exploitation of this vulnerability can lead to heap corruption, which is a significant risk for organizations that rely on this web browser for their operations.
The CVSS score for this vulnerability is 8.8, indicating a high severity level. The attack vector is network-based, and the complexity of exploitation is low, requiring no special privileges but necessitating user interaction. This combination of factors underscores the urgency for organizations to take immediate action.
Risk to organizations includes potential unauthorized access and data breaches, as attackers may leverage this vulnerability to execute arbitrary code or manipulate user data. Given the critical nature of this vulnerability, organizations are urged to prioritize patching immediately.
The vulnerability was published on November 14, 2018, and has been analyzed for its implications. Patching is critical, as failure to do so could lead to significant security incidents.
Vulnerability Details
The official description states that integer overflow in computing the required allocation size when instantiating a new JavaScript object in V8 allows a remote attacker to potentially exploit heap corruption via a crafted HTML page. This vulnerability is classified under CWE-190.
Affected versions include all versions of Google Chrome prior to 65.0.3325.146, as well as specific versions of Red Hat Enterprise Linux and Debian Linux.
Technical Analysis
The root cause of this vulnerability is an integer overflow that occurs when calculating the memory allocation size. Attackers can exploit this vulnerability by sending a specially crafted HTML page to users, who must interact with it to trigger the vulnerability. As a result, the attack vector is network-based, and the attack complexity is low. No privileges are required for exploitation, but user interaction is necessary.
The impact of this vulnerability is significant, as it affects confidentiality, integrity, and availability. Successful exploitation can lead to unauthorized access to sensitive information, modification of data, and denial of service.
Risk & Impact Analysis
Organizations face real-world deployment risks due to this vulnerability, as attackers may exploit it to gain unauthorized access or disrupt services. The blast radius potential is high, especially for organizations using web applications that rely on Google Chrome. Given the CVSS score of 8.8 and its inclusion in the Known Exploited Vulnerabilities (KEV) catalog, organizations should address this vulnerability in their priority patch cycle.
