- →The UAF is triggered via SVGAnimateElementBase::resetAnimatedType — monitor for SVG animate elements combined with DOM manipulation (node insertion/removal) during animation lifecycle events ↗
- →Exploit uses 'onfocusin' event handler on an HTML element to trigger DOM tree manipulation (appendChild/after) that races with SVG animation, causing the use-after-free ↗
- →The UAF is triggered through Node.after() DOM manipulation during a focusin event while SVG SMIL animations are active — look for SVG animate elements with concurrent focus-triggered DOM restructuring ↗
- →Impact is arbitrary code execution via maliciously crafted web content in WebKit — flag WebKit-based browsers (Safari, iOS WebView, iTunes, iCloud for Windows) processing SVG content with SMIL animations and dynamic DOM focus manipulation ↗
- ·Vulnerability affects WebKit versions prior to Safari 12, iOS 12, tvOS 12, iTunes 12.9 for Windows, and iCloud for Windows 7.7; patched in those releases ↗

CVE-2018-4191 WebKitGTK+ vulnerabilities
Title: WebKitGTK+ vulnerabilities
Summary: Several security issues were fixed in WebKitGTK+.
A large number of security issues were discovered in the WebKitGTK+ Web and
JavaScript engines. If a user were tricked into viewing a malicious
website, a remote attacker could exploit a variety of issues related to web
browser security, including cross-site scripting attacks, denial of service
attacks, and arbitrary code execution.
Instructions: This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart any applications
that use WebKitGTK+, such as Epiphany, to make all the necessary changes.

CVE-2018-4197 365 Days Later: Finding and Exploiting Safari Bugs using Publicly Available Tools - Project Zero
Posted by Ivan Fratric, Google Project Zero
Around a year ago, we published the results of research about the resilience of modern browsers against DOM fuzzing, a well-known technique for finding browser bugs. Together with the bug statistics we also published Domato, our DOM fuzzing tool that was used to find those bugs.
Given that in the previous research, Apple Safari, or more specifically, WebKit (its DOM engine) did noticeably worse than other browsers, we decided to revisit it after a year using exactly the same methodology and exactly the same tools to see whether anything changed.
Test Setup
As in the original research, the fuzzing was initially done against WebKitGTK+ and then all the crashes were tested against Apple Safari running on a Mac. This makes the fuzzing setup e
