Ubuntu 5.04 / 5.10 / 6.06 LTS : shadow vulnerability (USN-308-1)

Ubuntu Security Notice (C) 2006-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.

Synopsis :

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

Description :

Ilja van Sprundel discovered that passwd, when called with the -f, -g,
or -s option, did not check the result of the setuid() call. On
systems that configure PAM limits for the maximum number of user
processes, a local attacker could exploit this to execute chfn,
gpasswd, or chsh with root privileges.

This does not affect the default configuration of Ubuntu.

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 :

High / CVSS Base Score : 7.2

Family: Ubuntu Local Security Checks
