## Description

The extensions subsystem in Google Chrome before 53.0.2785.113 does not
properly restrict access to Object.prototype, which allows remote attackers
to load unintended resources, and consequently trigger unintended
JavaScript function calls and bypass the Same Origin Policy via an indirect
interception attack.
