The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4596-1 advisory.

    It was discovered that Tomcat did not properly manage HTTP/2 streams. An

    attacker could possibly use this to cause Tomcat to consume resources,

    resulting in a denial of service. (CVE-2020-11996)

    It was discovered that Tomcat did not properly release the HTTP/1.1

    processor after the upgrade to HTTP/2. An attacker could possibly use this to generate an     OutOfMemoryException, resulting in a denial of service.

    (CVE-2020-13934)

    It was discovered that Tomcat did not properly validate the payload length in a WebSocket frame. An     attacker could possibly use this to trigger an infinite loop, resulting in a denial of service.
    (CVE-2020-13935)

    It was discovered that Tomcat did not properly deserialize untrusted data. An attacker could possibly use     this issue to execute arbitrary code. (CVE-2020-9484)

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 number.
