"According to the versions of the pki-core packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - A vulnerability was found in all pki-core 10.x.x
    versions, where the Key Recovery Authority (KRA) Agent
    Service did not properly sanitize recovery request
    search page, enabling a Reflected Cross Site Scripting
    (XSS) vulnerability. An attacker could trick an
    authenticated victim into executing specially crafted
    Javascript code.(CVE-2019-10179)

  - A Reflected Cross Site Scripting flaw was found in all
    pki-core 10.x.x versions module from the pki-core
    server due to the CA Agent Service not properly
    sanitizing the certificate request page. An attacker
    could inject a specially crafted value that will be
    executed on the victim's browser.(CVE-2019-10146)

  - jQuery before 3.4.0, as used in Drupal, Backdrop CMS,
    and other products, mishandles jQuery.extend(true, {},
    ...) because of Object.prototype pollution. If an
    unsanitized source object contained an enumerable
    __proto__ property, it could extend the native
    Object.prototype.(CVE-2019-11358)
