A type confusion issue was addressed with improved memory handling. This issue is fixed in iOS 12.1.3, tvOS 12.1.2, Safari 12.0.3, iTunes 12.9.3 for Windows, iCloud for Windows 7.10. Processing maliciously crafted web content may lead to arbitrary code execution.

The version of Apple iOS running on the mobile device is prior to 12.1.3. It is, therefore, affected by multiple vulnerabilities:

 - Multiple unspecified vulnerabilities in WebKit can lead to arbitrary code execution if a user is enticed to visit a malicious web page. (CVE-2019-6227, CVE-2019-6233, CVE-2019-6234)

 - A maliciously crafted SQL query could lead to arbitrary code execution. (CVE-2018-20346, CVE-2018-20505, CVE-2018-20506)

 - A malicious application could lead to arbitrary code execution with kernel privileges. (CVE-2019-6218)

Additionally several other vulnerabilities exist, the highest of which could allow an attacker to perform a remote code execution attack by enticing a user to view malicious web content.

The version of Apple Safari installed on the remote host is prior to 12.0.3. It is, therefore, affected by the following vulnerabilities :

 - Input-validation errors exist that allow memory corruption leading to arbitrary code execution. (CVE-2019-6212, CVE-2019-6215, CVE-2019-6216, CVE-2019-6217, CVE-2019-6226, CVE-2019-6227, CVE-2019-6233, CVE-2019-6234)

 - Input-validation errors exist that allow an attacker to perform cross-site scripting attacks. (CVE-2019-6228, CVE-2019-6228)

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

The remote host is affected by the vulnerability described in GLSA-201903-12 (WebkitGTK+: Multiple vulnerabilities)

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

    An attacker could execute arbitrary code or conduct cross-site       scripting.
  Workaround :

    There is no known workaround at this time.

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

The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3889-1 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 iTunes installed on the remote Windows host is prior to 12.9.3. It is, therefore, affected by multiple vulnerabilities as referenced in the HT209450 advisory:

  - Multiple vulnerabilities exist due to input processing     flaws in the WebKit component. An attacker may be able     to leverage one of these vulnerability, by providing     maliciously crafted web content, to execute arbitrary     code on the host. (CVE-2019-6212, CVE-2019-6215,     CVE-2019-6216, CVE-2019-6217, CVE-2019-6226,     CVE-2019-6227, CVE-2019-6233, CVE-2019-6234)

  - A universal cross-site scripting vulnerability exists in     the WebKit component. An attacker may be able to leverage     this vulnerability, by providing maliciously crafted web     content, to execute arbitrary script code in the security     context of any site. (CVE-2019-6229)

  - A memory corruption vulnerability exists in the     AppleKeyStore component. An attacker may be able to     leverage this vulnerability to allow a process to     circumvent sandbox restrictions. (CVE-2019-6235)

  - An out-of-bounds read vulnerability exists in the     Core Media component. An attacker may be able to leverage     this vulnerability to allow a malicious application to     elevate its privileges. (CVE-2019-6221)

  - Multiple memory corruption issues exist in the SQLite     component. An attacker may be able to leverage these     vulnerabilities, by executing a malicious SQL query, to     execute arbitrary code on the host. (CVE-2018-20346,     CVE-2018-20505, CVE-2018-20506)


Note that Nessus has not tested for this issue 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 12.0.3. It is, therefore, affected by the following vulnerabilities :
