commandvar s = document.body.appendChild(document.createElement('script')); s.type = '0'; s.textContent = 'document.body.appendChild(parent.i0)'; var i0 = s.appendChild(document.createElement('iframe')); s.type = ''; var f = document.body.appendChild(document.createElement('iframe')); f.contentDocument.adoptNode(i0); f.src = 'about:blank';↗
- →Exploit triggers a use-after-free in WebKit's Document::adoptNode by appending an iframe inside a script element, changing the script type, then calling adoptNode on the iframe followed by navigating the parent frame to about:blank — monitor for DOM manipulation patterns combining adoptNode with dynamic script/iframe nesting. ↗
- →The use-after-free crash originates in WebCore::RenderWidget::setWidget when a RefPtr is set to nullptr after the underlying object has already been freed — this call chain can be used as a crash signature in WebContent process crash logs. ↗
- →The vulnerable XPC service process is com.apple.WebKit.WebContent.Development — monitor for unexpected crashes or memory corruption signals in this process. ↗
- →The freed memory region is a 1232-byte allocation; heap spray or UAF detection tooling targeting this allocation size in the WebContent process may aid in identifying exploitation attempts. ↗
- ·The exploit PoC targets a development/debug build of WebKit (WebKitBuild/Release) with AddressSanitizer instrumentation; behavior and offsets may differ in production Apple builds. ↗
- ·The vulnerability affects iOS before 10.3, Safari before 10.1, and tvOS before 10.2; systems running patched versions are not affected. ↗

WebKitGTK+ vulnerabilities
vendor_ubuntu·2017-04-10
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.
