Synopsis
========
Multiple vulnerabilities have been found in Puppet, the worst of which
could lead to execution of arbitrary code.

Background
==========
Puppet is a system configuration management tool written in Ruby.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-admin/puppet < 2.7.13 >= 2.7.13

Description
===========
Multiple vulnerabilities have been found in Puppet:

* Puppet uses predictable file names for temporary files
(CVE-2012-1906).
* REST requests for a file in a remote filebucket are not handled
properly by overriding filebucket storage locations (CVE-2012-1986).
* REST requests for a file in a remote filebucket are not handled
properly by reading streams or writing files on the Puppet master's
file system (CVE-2012-1987).
* File name paths are not properly sanitized from bucket requests
(CVE-2012-1988).
* The Telnet utility in Puppet does not handle temporary files securely
(CVE-2012-1989).

Impact
======
A local attacker with access to agent SSL keys could possibly execute
arbitrary code with the privileges of the process, cause a Denial of
Service condition, or perform symlink attacks to overwrite or read
arbitrary files on the Puppet master.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All Puppet users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/puppet-2.7.13"
