CVE-2008-2317: Apple Safari

High severity, CVSS 9.3. EPSS: 7.7% chance of exploitation in the next 30 days.

WebCore in Apple Safari does not properly perform garbage collection of JavaScript document elements, which allows remote attackers to execute arbitrary code or cause a denial of service (heap corruption and application crash) via a reference to the ownerNode property of a copied CSSStyleSheet object of a STYLE element, as originally demonstrated on Apple iPhone before 2.0 and iPod touch before 2.0, a different vulnerability than CVE-2008-1590.
