CVE-2016-5198

Published: 8 November 2016

V8 in Google Chrome prior to 54.0.2840.90 for Linux, and 54.0.2840.85 for Android, and 54.0.2840.87 for Windows and Mac included incorrect optimisation assumptions, which allowed a remote attacker to perform arbitrary read/write operations, leading to code execution, via a crafted HTML page.
