Detection & IOCsextracted from sources · hover to see the quote
- →The vulnerability is triggered via maliciously crafted web content processed by WebKit's WebCore::InlineTextBox::paint, resulting in an out-of-bounds read. Look for pages combining CSS properties -webkit-logical-width and -webkit-perspective with DOM manipulation (insertAdjacentHTML, appendChild, execCommand styleWithCSS) in JavaScript. ↗
- →The PoC uses document.execCommand('styleWithCSS', false, false) combined with DOM tree mutations (insertAdjacentHTML 'beforeBegin', appendChild) to trigger the memory corruption in the WebKit rendering pipeline. ↗
- →The crash originates in WebCore::RenderLayer::paintForegroundForFragments and propagates through the WebKit compositing/tiling layer stack. Monitor WebContent process crashes involving WebCore RenderLayer paint functions as a potential exploitation indicator. ↗
- →The vulnerable process is com.apple.WebKit.WebContent (WebContent XPC service). Monitor for abnormal crashes or memory violations in this process as an exploitation signal. ↗
- ·The vulnerability affects WebKit versions prior to iOS 12, tvOS 12, Safari 12, iTunes 12.9 for Windows, and iCloud for Windows 7.7. Detection should be scoped to unpatched versions of these products. ↗
- ·On Debian-based Linux systems (webkit2gtk), the vulnerability is resolved in version 2.22.0-2 across all tracked releases (bookworm, bullseye, forky, sid, trixie). ↗

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

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.
