The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:0120 advisory.

  - 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)

  - 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)

  - 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)

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

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 remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4335-1 advisory.

    Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially     crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of     service, obtain sensitive information, bypass security restrictions, bypass same-origin restrictions,     conduct cross-site scripting (XSS) attacks, or execute arbitrary code. (CVE-2019-11757, CVE-2019-11758,     CVE-2019-11759, CVE-2019-11760, CVE-2019-11761, CVE-2019-11762, CVE-2019-11763, CVE-2019-11764,     CVE-2019-17005, CVE-2019-17008, CVE-2019-17010, CVE-2019-17011, CVE-2019-17012, CVE-2019-17016,     CVE-2019-17017, CVE-2019-17022, CVE-2019-17024, CVE-2019-17026, CVE-2019-20503, CVE-2020-6798,     CVE-2020-6800, CVE-2020-6805, CVE-2020-6806, CVE-2020-6807, CVE-2020-6812, CVE-2020-6814, CVE-2020-6819,     CVE-2020-6820, CVE-2020-6821, CVE-2020-6825)

    It was discovered that NSS incorrectly handled certain memory operations. A remote attacker could     potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2019-11745)

    It was discovered that a specially crafted S/MIME message with an inner encryption layer could be     displayed as having a valid signature in some circumstances, even if the signer had no access to the     encrypted message. An attacker could potentially exploit this to spoof the message author.
    (CVE-2019-11755)

    A heap overflow was discovered in the expat library in Thunderbird. If a user were tricked in to opening a     specially crafted message, an attacker could potentially exploit this to cause a denial of service, or     execute arbitrary code. (CVE-2019-15903)

    It was discovered that Message ID calculation was based on uninitialized data. An attacker could     potentially exploit this to obtain sensitive information. (CVE-2020-6792)

    Mutiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially     crafted message, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information, or execute arbitrary code. (CVE-2020-6793, CVE-2020-6795, CVE-2020-6822)

    It was discovered that if a user saved passwords before Thunderbird 60 and then later set a primary     password, an unencrypted copy of these passwords would still be accessible. A local user could exploit     this to obtain sensitive information. (CVE-2020-6794)

    It was discovered that the Devtools Copy as cURL feature did not fully escape website-controlled     data. If a user were tricked in to using the Copy as cURL feature to copy and paste a command with     specially crafted data in to a terminal, an attacker could potentially exploit this to execute arbitrary     commands via command injection. (CVE-2020-6811)
