"According to the version of the xmlsec1 packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerability :

  - It was discovered xmlsec1's use of libxml2
    inadvertently enabled external entity expansion (XXE)
    along with validation. An attacker could craft an XML
    file that would cause xmlsec1 to try and read local
    files or HTTP/FTP URLs, leading to information
    disclosure or denial of service. (CVE-2017-1000061)
