Security: CPU overloading

Reported by vancouve...@gmail.com, Apr 21 2017

Issue description

This template is ONLY for reporting security bugs. If you are reporting a
Download Protection Bypass bug, please use the "Security - Download
Protection" template. For all other reports, please use a different
template.

Please READ THIS FAQ before filing a bug: https://www.chromium.org/Home
/chromium-security/security-faq

Please see the following link for instructions on filing security bugs:
http://www.chromium.org/Home/chromium-security/reporting-security-bugs

NOTE: Security bugs are normally made public once a fix has been widely
deployed.

VULNERABILITY DETAILS
Please provide a brief explanation of the security issue.

VERSION
Chrome Version: Version 58.0.3029.81 (64-bit)
Operating System: Windows 10 Home

REPRODUCTION CASE
When using the following link in my website
https://www.youtube.com/embed/WE_EgwFRils?list=PL3M4lKT4ssGRFn7YrLMzqhQI86kSXERNx

while I am signed up with my gmail account (vancouverbcd@gmail.com)
browser goes into infinite loop, throwing an error

remote.js:79 Uncaught TypeError: Cannot read property 'prototype' of undefined
    at Object.g.p (base.js:21)
    at remote.js:79
    at remote.js:166

That makes my CPU go to 100%. So basically, putting this link in a website - it 
automatically make all visitors that have the same gmail settings as I to 
make their computers overloaded.

FOR CRASHES, PLEASE INCLUDE THE FOLLOWING ADDITIONAL INFORMATION
Type of crash: CPU overload, infinite looping in youtube base.js file
Crash State: 

remote.js:79 Uncaught TypeError: Cannot read property 'prototype' of undefined
    at Object.g.p (base.js:21)

Thanks for the report, I'm unable to reproduce the issue. Can you please try with a clean profile and see if this still happens? Also note that we don't consider denial of service such as overloading the CPU as a security vulnerability.

^ To clarify, this could be caused by an extension. You'll want to try running this in a new browser profile with no extensions (incognito also works as long as you don't have any extensions running in incognito mode).
Yep, I tried to unistall all extension and problem still happens, the only think that affects it is my gmail account. (one of multiple I have, the rest don't cause this issue). So, whenever I sign out from my gmail account - the problem is gone.

Status: WontFix (was: Unconfirmed)
Thanks. It's difficult to say what's causing the problem only on your account. It's possible that a buggy Youtube experiment could be enabled on that account and is what's causing this problem.

Since overloading the CPU doesn't represent a security vulnerability I'm going to close this issue as WontFix. In the meanwhile you might want to consider reporting this to Youtube (I briefly searched and couldn't find a similar bug).
For the user it's basically the same as virus that eats all computer resources. I can not figure out what's the issue because it's all happening on your servers. I did not know how to categorize so I posted it here. If it happened to me it could happen to others and there is no reports because it's hard to recognize, exactly like any other virus, that is a security issue in my opinion.

One more thing: Are you seeing the same problem on other browsers? For example, does Firefox also print the "Cannot read property 'prototype' of undefined" message?
Let's put it this way, whoever figures out what setting it is and trick me out to set it up - will make my computer use 100% CPU and the suer will blame google - as it's their bug.
It happens in Chrome, Edge. Firefox works fine.
