  script_set_attribute(attribute:"description", value:
"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 :

  - 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)

  - A specially crafted request could have crashed the
    Apache HTTP Server prior to version 2.4.30, due to an
    out of bound access after a size limit is reached by
    reading the HTTP header. This vulnerability is
    considered very hard if not impossible to trigger in
    non-debug mode (both log and build level), so it is
    classified as low risk for common server
    usage.(CVE-2018-1301)

  - In Apache httpd 2.4.0 to 2.4.29, when mod_session is
    configured to forward its session data to CGI
    applications (SessionEnv on, not the default), a remote
    user may influence their content by using a 'Session'
    header. This comes from the 'HTTP_SESSION' variable
    name used by mod_session to forward its data to CGIs,
    since the prefix 'HTTP_' is also used by the Apache
    HTTP Server to pass HTTP header fields, per CGI
    specifications.(CVE-2018-1283)

  - mod_lua.c in the mod_lua module in the Apache HTTP
    Server 2.3.x and 2.4.x through 2.4.10 does not support
    an httpd configuration in which the same Lua
    authorization provider is used with different arguments
    within different contexts, which allows remote
    attackers to bypass intended access restrictions in
    opportunistic circumstances by leveraging multiple
    Require directives, as demonstrated by a configuration
    that specifies authorization for one group to access a
    certain directory, and authorization for a second group
    to access a second directory.(CVE-2014-8109)

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.");
