The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:0815 advisory.

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

  - 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 a device was changed while a stream was about to be destroyed, the <code>stream-reinit</code> 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)

  - 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)

  - 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)

  - 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)

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

The remote CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2020:0820 advisory.

  - usrsctp: Out of bounds reads in sctp_load_addresses_from_init() (CVE-2019-20503)

  - Mozilla: Use-after-free when removing data about origins (CVE-2020-6805)

  - Mozilla: BodyStream::OnInputStreamReady was missing protections against state confusion (CVE-2020-6806)

  - Mozilla: Use-after-free in cubeb during stream destruction (CVE-2020-6807)

  - Mozilla: Devtools' 'Copy as cURL' feature did not fully escape website-controlled data, potentially     leading to command injection (CVE-2020-6811)

  - Mozilla: The names of AirPods with personally identifiable information were exposed to websites with     camera or microphone permission (CVE-2020-6812)

  - Mozilla: Memory safety bugs fixed in Firefox 74 and Firefox ESR 68.6 (CVE-2020-6814)

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