Description Agostino Sarubbo gentoo-dev 2016-09-29 14:09:24 UTC
From ${URL} :

The problem is that you could sneak an unicode string terminator in the kdesu invocation
and the label showing which command will be executed ended there but we did execute the whole thing,
that is,
  
   echo Hi@; whoami > /tmp/filebyroot

If @ is the unicode string terminator would only tell the user kdesu would execute "echo Hi"
but would create the /tmp/filebyroot file as root

The fix is already available at
https://github.com/KDE/kde-cli-tools/commit/5eda179a099ba68a20dc21dc0da63e85a565a171
