Ubuntu 4.10 / 5.04 : sudo vulnerability (USN-142-1)

Ubuntu Security Notice (C) 2005-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Charles Morris discovered a race condition in sudo which could lead to
privilege escalation. If /etc/sudoers allowed a user the execution of
selected programs, and this was followed by another line containing
the pseudo-command 'ALL', that user could execute arbitrary commands
with sudo by creating symbolic links at a certain time.

Please note that this does not affect a standard Ubuntu installation.

Solution :

Update the affected sudo package.

Risk factor :

Low / CVSS Base Score : 3.7
(CVSS2#AV:L/AC:H/Au:N/C:P/I:P/A:P)
