TITLE

plural Apple Used in products WebKit Vulnerable to arbitrary code execution

DESCRIPTION

WebKit in Apple iOS before 10, tvOS before 10, iTunes before 12.5.1 on Windows, and Safari before 10 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, a different vulnerability than CVE-2016-4765, CVE-2016-4766, CVE-2016-4767, and CVE-2016-4768.
