Detection & IOCsextracted from sources · hover to see the quote
- →The vulnerability is a use-after-free (UAF) in WebKit's SVG animation handling, specifically triggered via the detachWrapper() code path during SVG SMIL animation processing. Detection should focus on crafted web content using SVG animate elements targeting list properties (e.g., SVGLengthList) with SMIL animations. ↗
- →The crash originates in WebCore's SVGListProperty::detachListWrappersAndResize and SVGAnimateElementBase::resetAnimatedType — process crash/memory corruption in com.apple.WebKit.WebContent.xpc (WebContent process) is a key indicator of exploitation attempts. ↗
- →Monitor for application crashes in the WebKit WebContent XPC service process (com.apple.WebKit.WebContent.Development / com.apple.WebKit.WebContent) as this is the process context where exploitation occurs. ↗
- →The vulnerability is triggered by processing maliciously crafted web content — network-level detection should look for pages delivering SVG content with SMIL animate elements targeting list-type attributes, delivered to Safari/WebKit-based browsers on unpatched Apple platforms (iOS < 11.2.5, macOS < 10.13.3, Safari < 11.0.3, tvOS < 11.2.5). ↗
- ·Affected platforms are iOS before 11.2.5, macOS before 10.13.3, Safari before 11.0.3, and tvOS before 11.2.5. Detection and patching scope should cover all four product lines. ↗
- ·On Debian-based Linux systems (webkit2gtk), the issue is resolved in version 2.18.6-1 across all tracked suites (bookworm, bullseye, forky, sid, trixie). ↗
