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

Ubuntu Security Notice (C) 2006-2013 Canonical, Inc. / NASL script (C) 2007-2013 Tenable Network Security, Inc.

Synopsis :

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

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.

Solution :

Update the affected login and / or passwd packages.

Risk factor :

High / CVSS Base Score : 7.2

Family: Ubuntu Local Security Checks
