Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : shadow vulnerability (USN-695-1)

Ubuntu Security Notice (C) 2008-2013 Canonical, Inc. / NASL script (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

Paul Szabo discovered a race condition in login. While setting up tty
permissions, login did not correctly handle symlinks. If a local
attacker were able to gain control of the system utmp file, they could
cause login to change the ownership and permissions on arbitrary
files, leading to a root privilege escalation.

Solution :

Update the affected login and / or passwd packages.

Risk factor :

High / CVSS Base Score : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
