vulnerabilities as referenced in the NXSA-AOS-6.5.5 advisory.

  - Incomplete Cleanup vulnerability in Apache Tomcat. The internal fork of Commons FileUpload packaged with
    Apache Tomcat 9.0.70 through 9.0.80 and 8.5.85 through 8.5.93 included an unreleased, in progress
    refactoring that exposed a potential denial of service on Windows if a web application opened a stream for
    an uploaded file but failed to close the stream. The file would never be deleted from disk creating the
    possibility of an eventual denial of service due to the disk being full. Users are recommended to upgrade
    to version 9.0.81 onwards or 8.5.94 onwards, which fixes the issue. (CVE-2023-42794)

  - Incomplete Cleanup vulnerability in Apache Tomcat.When recycling various internal objects in Apache Tomcat
    from 11.0.0-M1 through 11.0.0-M11, from 10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.80 and from
    8.5.0 through 8.5.93, an error could cause Tomcat to skip some parts of the recycling process leading to
    information leaking from the current request/response to the next. Users are recommended to upgrade to
    version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or 8.5.94 onwards, which fixes the issue.
    (CVE-2023-42795)

  - The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation
    can reset many streams quickly, as exploited in the wild in August through October 2023. (CVE-2023-44487)

  - Improper Input Validation vulnerability in Apache Tomcat.Tomcat from 11.0.0-M1 through 11.0.0-M11, from
    10.1.0-M1 through 10.1.13, from 9.0.0-M1 through 9.0.81 and from 8.5.0 through 8.5.93 did not correctly
    parse HTTP trailer headers. A specially crafted, invalid trailer header could cause Tomcat to treat a
    single request as multiple requests leading to the possibility of request smuggling when behind a reverse
    proxy. Users are recommended to upgrade to version 11.0.0-M12 onwards, 10.1.14 onwards, 9.0.81 onwards or
    8.5.94 onwards, which fix the issue. (CVE-2023-45648)

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