Ubuntu Security Notice (C) 2012-2013 Canonical, Inc. / NASL script (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

It was discovered that Puppet did not drop privileges when executing
commands as different users. If an attacker had control of the
execution manifests or the executed command, this could be used to
execute code with elevated group permissions (typically root).
(CVE-2012-1053)

It was discovered that Puppet unsafely opened files when the k5login
type is used to manage files. A local attacker could exploit this to
overwrite arbitrary files and escalate privileges. (CVE-2012-1054).

Solution :

Update the affected puppet-common package.

Risk factor :

Medium / CVSS Base Score : 6.9
(CVSS2#AV:L/AC:M/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 5.1
(CVSS2#E:U/RL:OF/RC:C)
Public Exploit Available : false
