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

  - A flaw was discovered in ibus that allows any
    unprivileged user to monitor and send method calls to
    the ibus bus of another user due to a misconfiguration
    in the DBus server setup. A local attacker may use this
    flaw to intercept all keystrokes of a victim user who
    is using the graphical interface, change the input
    method engine, or modify other input related
    configurations of the victim user.(CVE-2019-14822)

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.");
