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

Ubuntu Security Notice (C) 2014-2015 Canonical, Inc. / NASL script (C) 2014-2015 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.

Solution :

Update the affected puppet-common package.

Risk factor :

Medium / CVSS Base Score : 6.9
CVSS Temporal Score : 6.0
Public Exploit Available : true
