Impact

===== A context-dependent attacker could entice a user to open a specially crafted web site or JavaScript program using Chromium or V8, possibly resulting in the execution of arbitrary code with the privileges of the process, or a Denial of Service condition. The attacker also could cause a Java applet to run without user confirmation.

Workaround
