"The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 68.2. It is, therefore, affected
by multiple vulnerabilities as referenced in the mfsa2019-33 advisory, including the following:

  - In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to
    document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or
    XML_GetCurrentColumnNumber) could then result in a heap-based buffer over-read. (CVE-2019-15903)

  - A use-after-free vulnerability exists in IndexedDB when creating updates. When following the value's
    prototype chain, it was possible to retain a reference to a locale, delete it, and subsequently reference
    it. This resulted in a use-after-free and a potentially exploitable crash. (CVE-2019-11757)

  - A potential memory corruption vulnerability is present in the accessibility engine when 360 Total
    Security is installed, resulting in a potentially exploitable crash. (CVE-2019-11758)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
