From the description:
Web standards are ever-evolving and determine what browsers can do. But new features can also lead to new vulnerabilities as they exercise existing functionality in new and unexpected ways. This talk discusses some of the more interesting and unusual features of JavaScript, and how they lead to bugs in a variety of software, including Adobe Flash, Chrome, Microsoft Edge and Safari.
Natalie Silvanovich is a security researcher at Google Project Zero.
Whether you are looking for origin of bugs in a standard or playing the long game, creating the origin of bugs in standards (NSA for example), this is a must watch video!
A transcript with CVE links, etc, would be especially useful.
