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

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 83.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-50 advisory.

  - Mozilla developers Tyson Smith, Aaron Klotz, David Major and Jason Kratzer reported memory safety bugs     present in Firefox 82. Some of these bugs showed evidence of memory corruption and we presume that with     enough effort some of these could have been exploited to run arbitrary code. (CVE-2020-26969)

  - In Freetype, if PNG images were embedded into fonts, the <code>LoadSBitPng</code> function contained an     integer overflow that led to a heap buffer overflow, memory corruption, and an exploitable crash. Note:
    While Project Zero did discover instances of this vulnerability being exploited in the wild against     Chrome, in Firefox this vulnerability is only triggerable if a rarely-used, hidden preference is toggled,     and only affected Linux and Android operating systems. Other operating systems are unaffected; and Linux     and Android are unaffected in the default configuration. (CVE-2020-15999)

  - A parsing and event loading mismatch in Firefox's SVG code could have allowed load events to fire, even     after sanitization. An attacker already capable of exploiting an XSS vulnerability in privileged internal     pages could have used this attack to bypass our built-in sanitizer. (CVE-2020-26951)

  - Incorrect bookkeeping of functions inlined during JIT compilation could have led to memory corruption and     a potentially exploitable crash when handling out-of-memory errors. (CVE-2020-26952)

  - When drawing a transparent image on top of an unknown cross-origin image, the Skia library     <code>drawImage</code> function took a variable amount of time depending on the content of the underlying     image. This resulted in potential cross-origin information exposure of image content through timing side-     channel attacks. (CVE-2020-16012)

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