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

  - postgresql before versions 10.4, 9.6.9 is vulnerable in
    the adminpack extension, the
    pg_catalog.pg_logfile_rotate() function doesn't follow
    the same ACLs than pg_rorate_logfile. If the adminpack
    is added to a database, an attacker able to connect to
    it could exploit this to force log
    rotation.(CVE-2018-1115)

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.");
