Bug description:
  KDE Project Security Advisory
  =============================

  Title:          Plasma Desktop: Arbitrary command execution in the removable device notifier
  Risk Rating:    High
  CVE:            CVE-2018-6791
  Versions:       Plasma < 5.12.0
  Date:           8 February 2018

  
  Overview
  ========
  When a vfat thumbdrive which contains `` or $() in its volume label is plugged
  and mounted trough the device notifier, it's interpreted as a shell command,
  leaving a possibility of arbitrary commands execution. an example of offending
  volume label is "$(touch b)" which will create a file called b in the
  home folder.

  Workaround
  ==========
  Mount removable devices with Dolphin instead of the device notifier.

  Solution
  ========
  Update to Plasma >= 5.12.0 or Plasma >= 5.8.9

  Or apply the following patches:
  Plasma 5.8:

  KDE Project Security Advisory
  =============================

  Title:          Plasma: Notifications can expose user IP address
  Risk Rating:    Low
  CVE:            CVE-2018-6790
  Versions:       Plasma < 5.12.0
  Date:           8 February 2018

  
  Overview
  ========
  Plasma has support for the Desktop Nofications specification. That specification allows
  embedding images in notifications. Plasma was not sanitizing the HTML that forms the notification.
  That allowed for notifications to load a remote image leaking the user IP address. This is in turn
  made a bit worse by the fact that some chat software doesn't sanitize the text they send to the
  notification system either meaning that a third party could send a carefully crafted message
  to a chat room and get the IP addresses of the users in that chat room.

  Workaround
  ==========
  Disable notifications

  Solution
  ========
  Update to Plasma >= 5.12.0 or Plasma >= 5.8.9

  Or apply the following patches:
  Plasma 5.8: https://cgit.kde.org/plasma-workspace.git/commit/?h=Plasma/5.8&id=5bc696b5abcdb460c1017592e80b2d7f6ed3107c
