Detection & IOCsextracted from sources · hover to see the quote
- →Trigger requires accessibility features to be enabled (e.g., via Web Inspector/Error Console on Safari, or by default in WebKitGTK+); look for type confusion between RenderBox and RenderText triggered during layout with aria-labeledby attribute manipulation ↗
- →Exploit involves setting aria-labeledby attribute on an element and toggling a details/summary element's open state to trigger the type confusion during accessibility tree computation ↗
- →Crash occurs in WebCore::RenderBox::computeBlockDirectionMargins during layout triggered by accessibility label resolution (ariaLabeledByAttribute); monitor for crashes in this call chain as an exploitation indicator ↗
- →Vulnerability is exploitable via a crafted web page; network-level detection should flag delivery of HTML pages containing aria-labeledby attribute manipulation combined with details element open/close toggling in JavaScript ↗
- →WebKitGTK+ versions up to and including 2.14.2 are confirmed vulnerable; flag use of WebKitGTK+ < 2.14.4 in asset inventory ↗
- ·On Safari/Mac, the crash only triggers when Web Inspector or Error Console is open (which enables accessibility via AXObjectCache::enableAccessibility); exploitation in a standard browser session requires accessibility to be enabled by another means ↗
- ·On WebKitGTK+, accessibility is enabled by default, making all versions up to 2.14.2 unconditionally exploitable without any special user action ↗

CVE-2017-2350 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.
