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

  - Further techniques that built on the slipstream research combined with a malicious webpage could have
    exposed both an internal network's hosts as well as services running on the user's local machine. This
    vulnerability affects Firefox < 85. (CVE-2021-23961)

  - A texture upload of a Pixel Buffer Object could have confused the WebGL code to skip binding the buffer
    used to unpack it, resulting in memory corruption and a potentially exploitable information leak or crash.
    This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. (CVE-2021-23981)

  - Using techniques that built on the slipstream research, a malicious webpage could have scanned both an
    internal network's hosts as well as services running on the user's local machine utilizing WebRTC
    connections. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9.
    (CVE-2021-23982)

  - A malicious extension could have opened a popup window lacking an address bar. The title of the popup
    lacking an address bar should not be fully controllable, but in this situation was. This could have been
    used to spoof a website and attempt to trick the user into providing credentials. This vulnerability
    affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. (CVE-2021-23984)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 86 and Firefox ESR
    78.8. 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 < 78.9,
    Firefox < 87, and Thunderbird < 78.9. (CVE-2021-23987)

  - A WebGL framebuffer was not initialized early enough, resulting in memory corruption and an out of bound
    write. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88.
    (CVE-2021-23994)

  - When Responsive Design Mode was enabled, it used references to objects that were previously freed. We
    presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability
    affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. (CVE-2021-23995)

  - Through complicated navigations with new windows, an HTTP page could have inherited a secure lock icon
    from an HTTPS page. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88.
    (CVE-2021-23998)

  - If a Blob URL was loaded through some unusual user interaction, it could have been loaded by the System
    Principal and granted additional privileges that should not be granted to web content. This vulnerability
    affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. (CVE-2021-23999)

  - When a user clicked on an FTP URL containing encoded newline characters (%0A and %0D), the newlines would
    have been interpreted as such and allowed arbitrary commands to be sent to the FTP server. This
    vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. (CVE-2021-24002)

  - The WebAssembly JIT could miscalculate the size of a return type, which could lead to a null read and
    result in a crash. *Note: This issue only affected x86-32 platforms. Other platforms are unaffected.*.
    This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. (CVE-2021-29945)

  - Ports that were written as an integer overflow above the bounds of a 16-bit integer could have bypassed
    port blocking restrictions when used in the Alt-Svc header. This vulnerability affects Firefox ESR <
    78.10, Thunderbird < 78.10, and Firefox < 88. (CVE-2021-29946)

  - Mozilla developers reported memory safety bugs present in Firefox 88 and Firefox ESR 78.11. 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 < 78.11, Firefox < 89, and
    Firefox ESR < 78.11. (CVE-2021-29967)

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