The version of Firefox installed on the remote macOS or Mac OS X host is prior to 61.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2018-15 advisory.

  - Mozilla developers and community members Alex Gaynor, Christoph Diehl, Christian Holler, Jason Kratzer,     David Major, Jon Coppeard, Nicolas B. Pierron, Jason Kratzer, Marcia Knous, and Ronald Crane reported     memory safety bugs present in Firefox 60, Firefox ESR 60, and Firefox ESR 52.8. Some of these bugs showed     evidence of memory corruption and we presume that with enough effort that some of these could be exploited     to run arbitrary code. (CVE-2018-5188)

  - Windows 10 does not warn users before opening executable files with the <code>SettingContent-ms</code>     extension even when they have been downloaded from the internet and have the Mark of the Web. Without     the warning, unsuspecting users unfamiliar with this new file type might run an unwanted executable. This     also allows a WebExtension with the limited <code>downloads.open</code> permission to execute arbitrary     code without user interaction on Windows 10 systems  Note: this issue only affects Windows operating     systems. Other operating systems are unaffected. (CVE-2018-12368)

  - A buffer overflow can occur when rendering canvas content while adjusting the height and width of the     <code><canvas></code> element dynamically, causing data to be written outside of the currently     computed boundaries. This results in a potentially exploitable crash. (CVE-2018-12359)

  - A use-after-free vulnerability can occur when deleting an <code>input</code> element during a mutation     event handler triggered by focusing that element. This results in a potentially exploitable crash.
    (CVE-2018-12360)

  - An integer overflow can occur in the <code>SwizzleData</code> code while calculating buffer sizes. The     overflowed value is used for subsequent graphics computations when their inputs are not sanitized which     results in a potentially exploitable crash. (CVE-2018-12361)

Note that Nessus 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-201810-01 (Mozilla Firefox: Multiple vulnerabilities)

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

    A remote attacker could entice a user to view a specially crafted web       page, possibly resulting in the execution of arbitrary code with the       privileges of the process or a Denial of Service condition. Furthermore,       a remote attacker may be able to perform Man-in-the-Middle attacks,       obtain sensitive information, spoof the address bar, conduct clickjacking       attacks, bypass security restrictions and protection mechanisms, or have       other unspecified impact.
  Workaround :

    There is no known workaround at this time.

The version of Mozilla Firefox installed on the remote macOS or     Mac OS X host is prior to 61. It is, therefore, affected by multiple     critical and high severity vulnerabilities.

The version of Mozilla Firefox ESR installed on the remote macOS or Mac OS X host is prior to 52.9. It is, therefore, affected by multiple vulnerabilities, some of which allow code execution and potentially exploitable crashes.

The version of Mozilla Firefox installed on the remote Windows     host is prior to 61. It is, therefore, affected by multiple critical     and high severity vulnerabilities.

The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2018-2113 advisory.

    - Added fix for mozbz#1348168/CVE-2017-5428

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