Ubuntu 4.10 : passwd vulnerabilities (USN-17-1)

Ubuntu Security Notice (C) 2004-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected login and / or passwd packages.

Risk factor :

Medium / CVSS Base Score : 4.6
(CVSS2#AV:L/AC:L/Au:N/C:P/I:P/A:P)
