WebKit in Apple tvOS before 9.2.2 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site.

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

  - WebKit in Apple tvOS before 9.2.2 allows remote attackers to execute arbitrary code or cause a denial of     service (memory corruption) via a crafted web site. (CVE-2016-4588)

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

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3079-1 advisory.

    A large number of security issues were discovered in the WebKitGTK+ Web and JavaScript engines. If a user     were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related     to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary     code execution.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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