Package : shadow
Vulnerability : programming error
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2004-1001

A vulnerability has been discovered in the shadow suite which provides programs like chfn and chsh. It is possible for a user, who is logged in but has an expired password to alter his account information with chfn or chsh without having to change the password. The problem was originally thought to be more severe.

For the stable distribution (woody) this problem has been fixed in version 20000902-12woody1.

For the unstable distribution (sid) this problem has been fixed in version 4.0.3-30.3.

We recommend that you upgrade your passwd package (from the shadow suite).

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

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

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