otherWebCore::RenderObject Use-After-Free via CSS first-letter + accessibility aria-labeledby manipulation↗
commandCSS: text-transform:lowercase + ::first-letter{border-spacing:1em} + display:table-column-group + -webkit-appearance:menulist-button↗
commandaria-labeledby attribute set on dir element combined with appendChild of table row to trigger UAF↗
- →The UAF is triggered by combining CSS `::first-letter` pseudo-element with `display:table-column-group` and `-webkit-appearance:menulist-button` style properties on the same element, while accessibility (aria) attributes are manipulated in a DOM event handler — monitor for this combination in web content. ↗
- →The crash originates in WebCore::RenderBlock::createFirstLetterRenderer, indicating the free occurs during first-letter renderer creation; crash telemetry or ASan reports referencing this symbol indicate exploitation attempts. ↗
- →The freed 96-byte heap region at offset 40 (0x608000090ac8 inside [0x608000090aa0,0x608000090b00)) is characteristic of the RenderObject UAF; heap-spray or memory-tagging tooling should flag accesses to freed RenderObject allocations of this size. ↗
- →Exploit PoC uses an event handler (onload or similar) to call go() followed by eventhandler(), which moves a table row into a link element after style mutation — detect JavaScript that dynamically reassigns table rows into non-table elements alongside ARIA attribute writes. ↗
- ·The vulnerability requires accessibility features to be active in WebKit for the UAF to be reachable; the title explicitly states 'with Accessibility Enabled'. ↗
- ·Affected products span iOS <10.3.3, Safari <10.1.2, iCloud for Windows <6.2.2, iTunes for Windows <12.6.2, and tvOS <10.2.2; detection rules should account for all WebKit-embedding surfaces, not just Safari. ↗

WebKitGTK+ vulnerabilities
vendor_ubuntu·2017-08-02
CVE-2017-2538 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.
