"According to the versions of the httpd packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - In Apache HTTP Server 2.4.17 to 2.4.34, by sending
    continuous, large SETTINGS frames a client can occupy a
    connection, server thread and CPU time without any
    connection timeout coming to effect. This affects only
    HTTP/2 connections. A possible mitigation is to not
    enable the h2 protocol.(CVE-2018-11763)

  - In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38,
    with MPM event, worker or prefork, code executing in
    less-privileged child processes or threads (including
    scripts executed by an in-process scripting
    interpreter) could execute arbitrary code with the
    privileges of the parent process (usually root) by
    manipulating the scoreboard. Non-Unix systems are not
    affected.(CVE-2019-0211)

  - In Apache HTTP server versions 2.4.37 and prior, by
    sending request bodies in a slow loris way to plain
    resources, the h2 stream for that request unnecessarily
    occupied a server thread cleaning up that incoming
    data. This affects only HTTP/2 (mod_http2)
    connections.(CVE-2018-17189)

  - In Apache HTTP Server 2.4 releases 2.4.37 and 2.4.38, a
    bug in mod_ssl when using per-location client
    certificate verification with TLSv1.3 allowed a client
    to bypass configured access control
    restrictions.(CVE-2019-0215)

  - A vulnerability was found in Apache HTTP Server 2.4.0
    to 2.4.38. When the path component of a request URL
    contains multiple consecutive slashes ('/'), directives
    such as LocationMatch and RewriteRule must account for
    duplicates in regular expressions while other aspects
    of the servers processing will implicitly collapse
    them.(CVE-2019-0220)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
