USN-17-1: passwd vulnerability
Publication date
5 November 2004
Overview
passwd vulnerability
Releases
Details
Martin Schulze and Steve Grubb discovered a flaw in the authentication
input validation of the "chfn" and "chsh" programs. This allowed
logged in users with an expired password to change their real name and
their login shell without having to change their password.
This flaw cannot lead to privilege escalation and does not allow to
modify account properties of other users, so the impact is relatively
low.
