An issue was discovered in certain Apple products. iOS before 11.1 is affected. Safari before 11.0.1 is affected. iCloud before 7.1 on Windows is affected. iTunes before 12.7.1 on Windows is affected. tvOS before 11.1 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 triggered via SVG pattern element processing — specifically in WebCore::SVGPatternElement::collectPatternAttributes — causing a heap-buffer-overflow (out-of-bounds read). Detection should focus on crafted SVG content using <pattern> elements delivered via web pages.
  • The crash occurs in WebCore::SVGPatternElement::collectPatternAttributes — monitor for WebKit/WebCore crashes or ASan heap-buffer-overflow reports originating from SVGPatternElement rendering code paths.
  • Exploitation vector is a crafted web site — network-based detection should look for SVG payloads with nested or self-referencing <pattern> elements delivered over HTTP/HTTPS to unpatched WebKit-based browsers (iOS < 11.1, Safari < 11.0.1, tvOS < 11.1, iCloud for Windows < 7.1, iTunes for Windows < 12.7.1).
  • ·No network IOCs (domains, IPs, URLs), file hashes, or signatures are publicly associated with in-the-wild exploitation of this CVE. Detection must rely on behavioral/crash telemetry and SVG content heuristics.
  • ·The Debian webkit2gtk fix is tracked in version 2.18.1-1; environments running older webkit2gtk packages on Linux are also in scope despite this being primarily an Apple advisory.
