(Newt: User-assisted execution of arbitrary code)

    Miroslav Lichvar reported that Newt is prone to a heap-based buffer
    overflow in textbox.c.
  
Impact :

    A remote attacker could entice a user to enter a specially crafted
    string into a text dialog box rendered by Newt, possibly resulting in
    the remote execution of arbitrary code with the privileges of the user
    running the application, or a Denial of Service condition.
  
Workaround :

    There is no known workaround at this time."

"All Newt users should upgrade to the latest version:
    # emerge --sync

    NOTE: This is a legacy GLSA. Updates for all affected architectures are
    available since October 26, 2009. It is likely that your system is
    already no longer affected by this issue."
