Detection & IOCsextracted from sources · hover to see the quote
- →The exploit triggers a use-after-free in WebCore::DocumentLoader::frameLoader() by combining iframe navigation to a data: URL with a form submission and window.onbeforeunload handler that appends a DOM element, causing the FrameLoader to be accessed after being freed. ↗
- →The use-after-free crash occurs specifically in WebCore::DocumentLoader::frameLoader() const — monitor for WebKit/Safari crashes with this function in the stack trace as a sign of exploitation attempts. ↗
- →The freed memory originates from WebCore::ResourceLoader::releaseResources() via WTF::RefPtr::operator=(std::nullptr_t) — the object is freed during cancelMainResourceLoad then accessed in the subsequent frameLoader() call. ↗
- →Exploitation vector is processing maliciously crafted web content; look for Safari/WebKit process crashes (com.apple.WebKit.WebContent) combined with data: URL iframe navigations and form submissions in web logs or browser telemetry. ↗
- ·The exploit PoC was developed and tested against a local debug build of WebKit (WebKitBuild/Release), not a shipping binary; offsets and stack frames will differ in production Apple binaries. ↗
- ·Affected versions span multiple Apple products; patched versions are iOS 11.1, Safari 11.0.1, iCloud for Windows 7.1, iTunes 12.7.1 for Windows, and tvOS 11.1 — detections should account for all these surfaces. ↗

CVE-2017-13783 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.
