(Opera: Command-line URL shell command injection)

    Peter Zelezny discovered that the shell script used to launch
    Opera parses shell commands that are enclosed within backticks in the
    URL provided via the command line.
  
Impact :

    A remote attacker could exploit this vulnerability by enticing a
    user to follow a specially crafted URL from a tool that uses Opera to
    open URLs, resulting in the execution of arbitrary commands on the
    targeted machine.
  
Workaround :

    There is no known workaround at this time."
