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.
