An issue was discovered in certain Apple products. iOS before 10.3 is affected. Safari before 10.1 is affected. tvOS before 10.2 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.

Detection & IOCsextracted from sources · hover to see the quote
- →The vulnerability is a Use-After-Free in WebKit's ComposedTreeIterator::traverseNextInShadowTree, triggered by manipulating a details/summary element's 'open' attribute and innerHTML in a JavaScript onload handler, causing memory corruption via ContainerNode::removeChildren() freeing nodes still referenced by the iterator. ↗
- →The PoC trigger pattern involves toggling a <details> element's open property to false, setting innerHTML to replace children, then toggling open back to true inside an onload event — detect JavaScript that manipulates details/summary elements with rapid open/innerHTML/open sequences. ↗
- →The exploit is delivered via a crafted web page; network-level detection should look for pages serving HTML with <details> elements combined with onload JavaScript that modifies innerHTML and the open attribute in rapid succession. ↗
- ·The PoC exploit code targets a debug/ASan build of WebKit (WebKitBuild/Release with AddressSanitizer instrumentation); behavior and crash addresses will differ on production/release builds of Safari, iOS, and tvOS. ↗
- ·The vulnerability affects Apple WebKit as shipped in iOS before 10.3, Safari before 10.1, and tvOS before 10.2; the Debian webkit2gtk package was separately fixed in version 2.14.6-1. ↗

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.
