Yellow Dog Linux Security Advisory: YDU-20030607-2

[Terra Soft Security Team]

Yellow Dog Linux Security Announcement
--------------------------------------

Package:	hanterm-xf
Issue Date:	Jun 07,2003   
Priority:	medium
Advisory ID: 	YDU-20030607-2


1. 	Topic:

	Updated hanterm packages are available.


2. 	Problem:
	
	"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.  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.

	In addition, 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 with a backported security patch."
	
	(From Red Hat Advisory)

3. 	Solution:

   	a) Updating via apt...
   	We suggest that you use the apt-get program to keep your
   	system up-to-date. The following command(s) will retrieve
   	and install the fixed version of this update onto your system:

		apt-get update
		apt-get install hanterm-xf

   	b) Updating manually...
	Download the updates below and then run the following rpm command.
   	(Please use a mirror site)

		rpm -Fvh [filenames]
