The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5248-1 advisory.

    Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially     crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of     service, obtain sensitive information, trick a user into accepting unwanted permissions, conduct header     splitting attacks, conduct spoofing attacks, bypass security restrictions, confuse the user, or execute     arbitrary code. (CVE-2021-4129, CVE-2021-4140, CVE-2021-29981, CVE-2021-29982, CVE-2021-29987,     CVE-2021-29991, CVE-2021-38495, CVE-2021-38496, CVE-2021-38497, CVE-2021-38498, CVE-2021-38500,     CVE-2021-38501, CVE-2021-38503, CVE-2021-38504, CVE-2021-38506, CVE-2021-38507, CVE-2021-38508,     CVE-2021-38509, CVE-2021-43534, CVE-2021-43535, CVE-2021-43536, CVE-2021-43537, CVE-2021-43538,     CVE-2021-43539, CVE-2021-43541, CVE-2021-43542, CVE-2021-43543, CVE-2021-43545, CVE-2021-43656,     CVE-2022-22737, CVE-2022-22738, CVE-2022-22739, CVE-2022-22740, CVE-2022-22741, CVE-2022-22742,     CVE-2022-22743, CVE-2022-22745, CVE-2022-22747, CVE-2022-22748, CVE-2022-22751)

    It was discovered that Thunderbird ignored the configuration to require STARTTLS for an SMTP connection. A     person-in-the-middle could potentially exploit this to perform a downgrade attack in order to intercept     messages or take control of a session. (CVE-2021-38502)

    It was discovered that JavaScript was unexpectedly enabled in the composition area. An attacker could     potentially exploit this in combination with another vulnerability, with unspecified impacts.
    (CVE-2021-43528)

    A buffer overflow was discovered in the Matrix chat library bundled with Thunderbird. An attacker could     potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2021-44538)

    It was discovered that Thunderbird's OpenPGP integration only considered the inner signed message when     checking signature validity in a message that contains an additional outer MIME layer. An attacker could     potentially exploit this to trick the user into thinking that a message has a valid signature.
    (CVE-2021-4126)
