CVE-2016-5198
Google Chromium V8 Out-of-Bounds Memory Vulnerability
Does this matter?
Known to be exploited in the wild (CISA KEV, CISA remediation deadline 22 June 2022). Treat as an emergency change: patch or isolate now, then hunt for prior compromise.
Description
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.
