An issue was discovered in certain Apple products. Safari before 11.1 is affected. The issue involves the "WebKit" component. A Safari cross-site scripting (XSS) vulnerability allows remote attackers to inject arbitrary web script or HTML via a crafted URL.

The version of Apple Safari installed on the remote host is prior to 11.1. It is, therefore, affected by multiple vulnerabilities as described in the HT208695 security advisory.

This update for webkit2gtk3 to version 2.20.3 fixes the issues :

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is affected by the vulnerability described in GLSA-201808-04 (WebkitGTK+: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in WebKitGTK+. Please       review the referenced CVE identifiers for details.
  Impact :

    A remote attacker could execute arbitrary commands or cause a denial of       service condition  via a maliciously crafted web content.
  Workaround :

    There is no known workaround at this time.

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3635-1 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.

The version of Apple Safari installed on the remote macOS or Mac OS X host is prior to 11.1. It is, therefore, affected by multiple vulnerabilities as described in the HT208695 security advisory.
