The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3303-1 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.

The version of Apple Safari installed on the remote macOS or Mac OS X host is prior to 10.1.1. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified flaw exists in the history menu     functionality. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition.
    (CVE-2017-2495)

  - Multiple memory corruption issues exist in the WebKit     component due to improper validation of user-supplied     input. An unauthenticated, remote attacker can exploit     these issues, by convincing a user to visit a specially     crafted website, to execute arbitrary code.

  - Multiple universal cross-site scripting (XSS)     vulnerabilities exist in WebKit due to improper handling     of WebKit Editor commands, container nodes, pageshow     events, frame loading, and cached frames. An     unauthenticated, remote attacker can exploit this, via a     specially crafted web page, to execute arbitrary script     code in a user's browser session.

This update was imported from the SUSE:SLE-12-SP2:Update update project.

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

  - An issue was discovered in certain Apple products. iOS before 10.3.2 is affected. Safari before 10.1.1 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.
    (CVE-2017-2496)

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

The version of Apple iOS running on the mobile device is prior to 10.3.2. It is, therefore, affected by multiple vulnerabilities :

  - Multiple memory corruption issues exist in the WebKit     component due to improper validation of user-supplied     input. An unauthenticated, remote attacker can exploit     these issues, by convincing a user to visit a specially     crafted website, to execute arbitrary code.

  - Multiple information disclosure vulnerabilities exist     in the Kernel component due to improper sanitization of     user-supplied input. A local attacker can exploit these     to read the contents of restricted memory.
    (CVE-2017-2507, CVE-2017-6987)

  - A use-after-free error exists in the SQLite component     when handling SQL queries. An unauthenticated, remote     attacker can exploit this to deference already freed     memory, resulting in the execution of arbitrary code.
    (CVE-2017-2513)

  - Multiple buffer overflow conditions exist in the SQLite     component due to the improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit these, via a specially crafted SQL query, to     execute arbitrary code. (CVE-2017-2518, CVE-2017-2520)

  - A memory corruption issue exists in the SQLite component     when handling SQL queries. An unauthenticated, remote     attacker can exploit this, via a specially crafted SQL     query, to execute arbitrary code. (CVE-2017-2519)

Versions of Safari prior to 10.1.1 are affected by multiple vulnerabilities :

 - A flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A use-after-free error exists in the handling of RenderElement objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A use-after-free error exists in the handling of RenderLayer objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A use-after-free error exists in the handling of RenderInline objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - An unspecified flaw exists in the Safari history menu. With a specially crafted web page, a context-dependent attacker can cause an application denial of service.
 - A flaw exists related to an inconsistent user interface. This may allow a context-dependent attacker to spoof the address bar.
 - A logic flaw exists that allows a UXSS attack. The issue is triggered when handling container nodes. This may allow a context-dependent attacker to create a specially crafted web page that will execute arbitrary script code in a user's browser session within the trust relationship between their browser and any website.
 - A flaw exists related to an inconsistent user interface. This may allow a context-dependent attacker to spoof the address bar.

This product is also affected by vulnerabilities found in the following components:

 - WebKit 
 - Web Inspector

The version of iOS running on the mobile device is prior to 10.3.2, and is affected by multiple vulnerabilities :

 - A use-after-free error exists in the handling of RenderElement objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A use-after-free error exists in the handling of RenderLayer objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A use-after-free error exists in the handling of RenderInline objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - An unspecified flaw exists related to the certificate trust policy that is triggered when handling trust acceptance. This may allow a context-dependent attacker to potentially cause untrusted certificates to be treated as trusted.
 - An unspecified flaw exists in the Safari history menu. With a specially crafted web page, a context-dependent attacker can cause an application denial of service.
 - A logic flaw exists that allows a universal cross-site scripting (UXSS) attack. The issue is triggered when handling WebKit Editor commands. This may allow a context-dependent attacker to create a specially crafted web page that will execute arbitrary script code in a user's browser session within the trust relationship between their browser and any website.
 - A type confusion flaw exists in SQLite that is triggered as certain input related to 'snippet' is not properly validated. With specially crafted web content, a context-dependent attacker can corrupt memory and potentially execute arbitrary code.
