Ubuntu 12.04 LTS / 12.10 / 13.04 / 13.10 : puppet regression (USN-2077-2)

Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

USN-2077-1 fixed a vulnerability in Puppet. The upstream patch
introduced a regression resulting in the default file mode being
incorrect. This update fixes the problem.

We apologize for the inconvenience.

It was discovered that Puppet incorrectly handled temporary files. A
local attacker could possibly use this issue to overwrite arbitrary
files. In the default installation of Ubuntu, this should be prevented
by the Yama link restrictions.

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 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 : 6.0
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
