"The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in
the USN-4202-1 advisory.

    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)

    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, 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)

    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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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