Detection & IOCsextracted from sources · hover to see the quote
- →The use-after-free is triggered via a crafted web page combining CSS `-webkit-border-image` with `-webkit-flow-into` on a table element, followed by `document.execCommand('selectAll')`, slot reassignment, and `table.deleteCaption()` to free the caption node while a reference is still held. ↗
- →Garbage collector is deliberately triggered in a loop after `deleteCaption()` to force the UAF condition; monitor for tight JS loops immediately following DOM table caption deletion combined with CSS named flows. ↗
- ·The exploit PoC targets a debug/ASan build of WebKit from the Project Zero researcher's local environment; offsets and framework paths in the stack trace are build-specific and not directly applicable to production Apple binaries. ↗
- ·Affected versions are iOS before 10.3, Safari before 10.1, and watchOS before 3.2; systems patched to these versions or later are not vulnerable. ↗

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.
