USN17-1 : passwd vulnerabilities

Vulnerability Assessment Summary
passwd vulnerabilities

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- login
- passwd

Description :

Martin Schulze and Steve Grubb discovered a flaw in the authentication
input validation of the "chfn" and "chsh" programs. This permited
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 permit to
modify account properties of other users, so the impact is relatively
low.

Solution :

Upgrade to :
- login-4.0.3-28.5ubuntu6.1 (Ubuntu 4.10)
- passwd-4.0.3-28.5ubuntu6.1 (Ubuntu 4.10)

Network Security Threat Level: High
