WebKit, as used in Apple iOS before 8.1.3; Apple Safari before 6.2.3, 7.x before 7.1.3, and 8.x before 8.0.3; and Apple TV before 7.0.3, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site, a different vulnerability than CVE-2014-4477 and CVE-2014-4479.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - WebKit, as used in Apple iOS before 8.1.3; Apple Safari before 6.2.3, 7.x before 7.1.3, and 8.x before     8.0.3; and Apple TV before 7.0.3, allows remote attackers to execute arbitrary code or cause a denial of     service (memory corruption and application crash) via a crafted web site, a different vulnerability than     CVE-2014-4477 and CVE-2014-4479. (CVE-2014-4476)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Apple iTunes running on the remote host is prior to 12.2. It is, therefore, affected by multiple vulnerabilities due to memory corruption issues in the WebKit component. An attacker can exploit these to cause a denial of service or execute arbitrary code.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Apple iTunes installed on the remote Windows host is prior to 12.2. It is, therefore, affected by multiple vulnerabilities in the bundled version of WebKit, including denial of service and arbitrary code execution vulnerabilities.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Safari browser is missing a security update to Webkit.  Apple Safari is bundled with Apple WebKit.  Apple WebKit is affected by three distinct flaws.  These flaws are based on the way that Apple WebKit handles specially crafted web sites.  While the details of these vulnerabilities are currently unknown, the vendor has acknowledged that all three vulnerabilities could result in a remote attacker executing arbitrary code.

According to its banner, the remote Apple TV device is missing a security update.  It is, therefore, affected by the following vulnerabilities :

 - Apple TV is bundled with Apple WebKit.  Apple WebKit is affected by several vulnerabilities which would allow a remote attacker to execute arbitrary code or crash the application. (CVE-2014-4476, CVE-2014-4477, CVE-2014-4459, CVE-2014-4479)
