The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has firefox packages installed that are affected by multiple vulnerabilities:

  - When removing data about an origin whose tab was recently closed, a use-after-free could occur in the     Quota manager, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird <     68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. (CVE-2020-6805)

  - By carefully crafting promise resolutions, it was possible to cause an out-of-bounds read off the end of     an array resized during script execution. This could have led to memory corruption and a potentially     exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and     Firefox ESR < 68.6. (CVE-2020-6806)

  - When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer does not     escape < and > characters. Because the resulting string is pasted directly into the text node of the     element this does not result in a direct injection into the webpage; however, if a webpage subsequently     copies the node's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability.
    Two WYSIWYG editors were identified with this behavior, more may exist. This vulnerability affects Firefox     ESR < 68.4 and Firefox < 72. (CVE-2019-17022)

  - When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer incorrectly     rewrites a @namespace rule. This could allow for injection into certain types of websites resulting in     data exfiltration. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72. (CVE-2019-17016)

  - Due to a missing case handling object types, a type confusion vulnerability could occur, resulting in a     crash. We presume that with enough effort that it could be exploited to run arbitrary code. This     vulnerability affects Firefox ESR < 68.4 and Firefox < 72. (CVE-2019-17017)

  - Mozilla developers reported memory safety bugs present in Firefox 71 and Firefox ESR 68.3. 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. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.
    (CVE-2019-17024)

  - Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type     confusion. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects     Firefox ESR < 68.4.1, Thunderbird < 68.4.1, and Firefox < 72.0.1. (CVE-2019-17026)

  - A content process could have modified shared memory relating to crash reporting information, crash itself,     and cause an out-of-bound write. This could have caused memory corruption and a potentially exploitable     crash. This vulnerability affects Firefox < 73 and Firefox < ESR68.5. (CVE-2020-6796)

  - If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and     execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer     a cross-site scripting vulnerability as a result. In general, this flaw cannot be exploited through email     in the Thunderbird product because scripting is disabled when reading mail, but is potentially a risk in     browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox     < ESR68.5. (CVE-2020-6798)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firefox ESR     68.4. 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. In general, these flaws cannot be exploited     through email in the Thunderbird product because scripting is disabled when reading mail, but are     potentially risks in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5,     Firefox < 73, and Firefox < ESR68.5. (CVE-2020-6800)

  - The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP method of a request,     which can be controlled by the website. If a user used the 'Copy as Curl' feature and pasted the command     into a terminal, it could have resulted in command injection and arbitrary command execution. This     vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6.
    (CVE-2020-6811)

  - usrsctp before 2019-12-20 has out-of-bounds reads in sctp_load_addresses_from_init. (CVE-2019-20503)

  - The first time AirPods are connected to an iPhone, they become named after the user's name by default     (e.g. Jane Doe's AirPods.) Websites with camera or microphone permission are able to enumerate device     names, disclosing the user's name. To resolve this issue, Firefox added a special case that renames     devices containing the substring 'AirPods' to simply 'AirPods'. This vulnerability affects Thunderbird <     68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. (CVE-2020-6812)

  - When a device was changed while a stream was about to be destroyed, the stream-reinit task     may have been executed after the stream was destroyed, causing a use-after-free and a potentially     exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and     Firefox ESR < 68.6. (CVE-2020-6807)

  - Mozilla developers reported memory safety bugs present in Firefox and Thunderbird 68.5. 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. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox <     ESR68.6, and Firefox ESR < 68.6. (CVE-2020-6814)

  - Under certain conditions, when running the nsDocShell destructor, a race condition can cause a use-after-     free. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects     Thunderbird < 68.7.0, Firefox < 74.0.1, and Firefox ESR < 68.6.1. (CVE-2020-6819)

  - Under certain conditions, when handling a ReadableStream, a race condition can cause a use-after-free. We     are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Thunderbird <     68.7.0, Firefox < 74.0.1, and Firefox ESR < 68.6.1. (CVE-2020-6820)

  - When reading from areas partially or fully outside the source resource with WebGL's     copyTexSubImage method, the specification requires the returned values be zero. Previously,     this memory was uninitialized, leading to potentially sensitive data disclosure. This vulnerability     affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. (CVE-2020-6821)

  - On 32-bit builds, an out of bounds write could have occurred when processing an image larger than 4 GB in     GMPDecodeData. It is possible that with enough effort this could have been exploited to run     arbitrary code. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75.
    (CVE-2020-6822)

  - Mozilla developers and community members Tyson Smith and Christian Holler reported memory safety bugs     present in Firefox 74 and Firefox ESR 68.6. 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. This     vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. (CVE-2020-6825)

  - A race condition when running shutdown code for Web Worker led to a use-after-free vulnerability. This     resulted in a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76,     and Thunderbird < 68.8.0. (CVE-2020-12387)

  - A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to     memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8,     Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-6831)

  - The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP POST data of a     request, which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the     command into a terminal, it could have resulted in the disclosure of local files. This vulnerability     affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-12392)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 75 and Firefox ESR     68.7. 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. This vulnerability affects Firefox ESR < 68.8,     Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-12395)

The remote host is affected by the vulnerability described in GLSA-202003-02 (Mozilla Firefox: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox. Please       review the CVE identifiers referenced below 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 Firefox ESR installed on the remote macOS or Mac OS X host is prior to 68.4. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2020-06 advisory. Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
