The version of Firefox installed on the remote macOS or Mac OS X host is prior to 70.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-34 advisory, including the following:

  - Incorrect derivation of a packet length in WebRTC in Google Chrome prior to 68.0.3440.75 allowed a remote     attacker to potentially exploit heap corruption via a crafted video file. (CVE-2018-6156)

  - 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)     then resulted in a heap-based buffer over-read. (CVE-2019-15903)

  - When storing a value in IndexedDB, the value's prototype chain is followed and 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)

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