(Xfce Terminal: Remote arbitrary code execution)

    Lasse Karkkainen discovered that the function terminal_helper_execute()
    in file terminal-helper.c does not properly escape the URIs before
    processing.
  
Impact :

    A remote attacker could entice a user to open a specially crafted link,
    possibly leading to the remote execution of arbitrary code with the
    privileges of the user running Xfce Terminal. Note that the exploit
    code depends on the browser used to open the crafted link.
  
Workaround :

    There is no known workaround at this time."
