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.

The version of Apple iOS running on the mobile device is prior to 11.1. It is, therefore, affected by multiple vulnerabilities as referenced in the HT208222 advisory.

The version of Apple Safari installed on the remote host is prior to 11.0.1. It is, therefore, affected by multiple vulnerabilities as described in the HT208223 security advisory.

The WebKit team reports many vulnerabilities.
