Debian Security Advisory DSA 675-1                                        Martin Schulze
February 10th, 2005

Package        : hztty
Vulnerability  : privilege escalation
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2005-0019

Erik Sjölund discovered that hztty, a converter for GB, Big5 and zW/HZ
Chinese encodings in a tty session, can be triggered to execute
arbitrary commands with group utmp privileges.

For the stable distribution (woody) this problem has been fixed in
version 2.0-5.2woody2.

For the unstable distribution (sid) this problem has been fixed in
version 2.0-6.1.

We recommend that you upgrade your hztty package.

Upgrade Instructions
- --------------------

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.
