Integer overflow in V8 object instantiation in Google Chrome
CVE-2018-6065 is an integer overflow vulnerability in the V8 JavaScript engine in Google Chrome prior to 65.0.3325.146. The flaw occurs while computing the required allocation size when instantiating a new JavaScript object. A crafted HTML page containing malicious JavaScript can trigger the overflow, leading to an undersized heap allocation and subsequent heap corruption during object creation. The issue is remotely reachable through web content rendered by a vulnerable Chrome/Chromium-based browser instance.
