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

  - In systemd through 233, certain sizes passed to     dns_packet_new in systemd-resolved can cause it to     allocate a buffer that's too small. A malicious DNS     server can exploit this via a response with a specially     crafted TCP payload to trick systemd-resolved into     allocating a buffer that's too small, and subsequently     write arbitrary data beyond the end of     it.(CVE-2017-9445)

An update of the systemd package has been released.

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

  - An out-of-bounds write flaw was found in the way     systemd-resolved daemon handled processing of DNS     responses. A remote attacker could potentially use this     flaw to crash the daemon or execute arbitrary code in     the context of the daemon process.i1/4^CVE-2017-9445i1/4%0
