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.

Multiple security issues have been found in the Mozilla Firefox web browser, which could potentially result in the execution of arbitrary code, data exfiltration or cross-site scripting.

For Debian 8 'Jessie', these problems have been fixed in version 68.4.0esr-1~deb8u1.

We recommend that you upgrade your firefox-esr packages.

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)
