Vulnerability Assessment Summary
Check for the version of the hanterm packages

Detailed Explanation for this Vulnerability Assessment

Updated Hangul Terminal packages fix two security issues.

Hangul Terminal is a terminal emulator for the X Window System, based on
Xterm.

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. A possible hacker 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.

Users are advised to upgrade to these erratum packages, which contain
Hangul Terminal version 2.0.5 which is not vulnerable to these issues.
