--change-stack-guard-on-fork

What does --change-stack-guard-on-fork do?

After a zygote forks a new process, change the stack canary. This switch is useful so not all forked processes use the same canary (a secret value), which can be vulnerable to information leaks and brute force attacks. See https://crbug.com/1206626. This requires that all functions on the stack at the time content::RunZygote() is called be compiled without stack canaries. Valid values are "enable" or "disable".

Usage

chrome --change-stack-guard-on-fork

const browser = await puppeteer.launch({
  args: ['--change-stack-guard-on-fork']
});

const browser = await chromium.launch({
  args: ['--change-stack-guard-on-fork']
});

from selenium import webdriver

options = webdriver.ChromeOptions()
options.add_argument('--change-stack-guard-on-fork')

driver = webdriver.Chrome(options=options)
