Package : hanterm Vulnerability : buffer overflow Problem-Type : local Debian-specific: no

A set of buffer overflow problems have been found in hanterm, a Hangul terminal for X11 derived from xterm, that will read and display Korean characters in its terminal window. The font handling code in hanterm uses hard limited string variables but didn't check for boundaries.

This problem can be exploited by a malicious user to gain access to the utmp group which is able to write the wtmp and utmp files. These files record login and logout activities.

This problem has been fixed in version 3.3.1p17-5.2 for the stable Debian distribution. A fixed package for the current testing/unstable distribution is not yet available but will have a version number higher than 3.3.1p18-6.1.

We recommend that you upgrade your hanterm packages immediately if you have them installed. Known exploits are already available.

wget url will fetch the file for you dpkg -i file.deb will install the referenced file.

If you are using the apt-get package manager, use the line for sources.list as given below:

apt-get update will update the internal database apt-get upgrade will install corrected packages

You may use an automated update by adding the resources from the footer to the proper configuration.
