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)
