Description Mark J. Cox 2003-02-25 11:10:58 UTC
Hangul Terminal provides an escape sequence for reporting the current
window title which essentially takes the current title and places it
directly on the command line. An attacker can craft an escape sequence
that sets the window title of a victim using Hangul Terminal to an
arbitrary command and then report it to the command line. Since it is not
possible to embed a carriage return into the window title the attacker
would then have to convince the victim to press Enter for it to process the
title as a command, although the attacker could craft other escape
sequences that might convince the victim to do so.

It is possible to lock up Hangul Terminal before version 2.0.5 by sending
an invalid DEC UDK escape sequence.
