"According to the version of the ipa packages installed, the EulerOS
installation on the remote host is affected by the following
vulnerability :

  - A flaw was found in IPA, all 4.6.x versions before
    4.6.7, all 4.7.x versions before 4.7.4 and all 4.8.x
    versions before 4.8.3, in the way the internal function
    ber_scanf() was used in some components of the IPA
    server, which parsed kerberos key data. An
    unauthenticated attacker who could trigger parsing of
    the krb principal key could cause the IPA server to
    crash or in some conditions, cause arbitrary code to be
    executed on the server hosting the IPA
    server.(CVE-2019-14867)

Note that Tenable Network Security has extracted the preceding
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.");
