- →Exploit triggers a WebKit RenderLayer Use-After-Free by combining CSS -webkit-flow-into property manipulation, execCommand('fontSize'), requestAnimationFrame callback, Shadow DOM attachment (attachShadow), and DOM node replacement (replaceWith) in sequence to corrupt memory during garbage collection sweep. ↗
- →Crash occurs inside JSC::MarkedBlock::Handle::sweep during garbage collection triggered by the exploit's loop, indicating the use-after-free is reached via the JSC heap sweeper — monitor for renderer crashes originating from JavaScriptCore GC sweep paths following Shadow DOM / CSS named flow manipulation. ↗
- ·Vulnerability is fixed in iOS 10.3, Safari 10.1, and tvOS 10.2; exploit only affects unpatched versions of these Apple products. ↗
- ·Debian WebKitGTK packages are resolved/fixed at version 2.16.3-2 across all tracked branches (bookworm, bullseye, forky, sid, trixie). ↗

CVE-2016-9642 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.
