  Title:  Ark: unintended execution of scripts and executable files
  Risk Rating:Important
  CVE:CVE-2017-5330
  Versions:   ark >= 15.12
  Author: Elvis Angelaccio 
  Date:   12 January 2017

  Overview
  

  Through a (possibly malicious) tar archive that contains an
  executable shell script or binary, it was possible to execute
  arbitrary code on target machines.
  KRun::runUrl() has a runExecutable argument which defaults to true.
  Ark was using this default value and was also not checking
  whether an extracted file was executable before passing it to the
  runUrl() function.

  Impact
  ==

  An attacker can send legitimate tar archives with executable scripts or
  binaries disguised as normal files (say, with README or LICENSE as filenames).
  The attacker then can trick a user to select those files and click
  the Open button in the Ark toolbar, which triggers the affected code.

  Workaround
  ==

  Don't use the File -> Open functionality of Ark.
  You can still open archives (Archive->Open) and extract them.

  Solution
  

  Update to Ark >= 16.12.1

  For older releases of Ark, apply the following patches:

  Applications/16.08 branch: 
https://commits.kde.org/ark/49ce94df19607e234525afda5ad4190ce35300c3
  Applications/16.04 branch:
