"Multiple vulnerabilities were discovered in Puppet, a centralized
configuration management system.

  - CVE-2013-1640
    An authenticated malicious client may request its
    catalog from the puppet master, and cause the puppet
    master to execute arbitrary code. The puppet master must
    be made to invoke the 'template' or 'inline_template'
    functions during catalog compilation.

  - CVE-2013-1652
    An authenticated malicious client may retrieve catalogs
    from the puppet master that it is not authorized to
    access. Given a valid certificate and private key, it is
    possible to construct an HTTP GET request that will
    return a catalog for an arbitrary client.

  - CVE-2013-1653
    An authenticated malicious client may execute arbitrary
    code on Puppet agents that accept kick connections.
    Puppet agents are not vulnerable in their default
    configuration. However, if the Puppet agent is
    configured to listen for incoming connections, e.g.
    listen = true, and the agent's auth.conf allows access
    to the 'run' REST endpoint, then an authenticated client
    can construct an HTTP PUT request to execute arbitrary
    code on the agent. This issue is made worse by the fact
    that puppet agents typically run as root.

  - CVE-2013-1654
    A bug in Puppet allows SSL connections to be downgraded
    to SSLv2, which is known to contain design flaw
    weaknesses. This affects SSL connections between puppet
    agents and master, as well as connections that puppet
    agents make to third-party servers that accept SSLv2
    connections. Note that SSLv2 is disabled since OpenSSL
    1.0.

  - CVE-2013-1655
    An unauthenticated malicious client may send requests to
    the puppet master, and have the master load code in an
    unsafe manner. It only affects users whose puppet
    masters are running ruby 1.9.3 and above.

  - CVE-2013-2274
    An authenticated malicious client may execute arbitrary
    code on the puppet master in its default configuration.
    Given a valid certificate and private key, a client can
    construct an HTTP PUT request that is authorized to save
    the client's own report, but the request will actually
    cause the puppet master to execute arbitrary code.

  - CVE-2013-2275
    The default auth.conf allows an authenticated node to
    submit a report for any other node, which is a problem
    for compliance. It has been made more restrictive by
    default so that a node is only allowed to save its own
    report."

"Moses Mendoza reports :

A vulnerability found in Puppet could allow an authenticated client to
cause the master to execute arbitrary code while responding to a
catalog request. Specifically, in order to exploit the vulnerability,
the puppet master must be made to invoke the 'template' or
'inline_template' functions during catalog compilation.

A vulnerability found in Puppet could allow an authenticated client to
connect to a puppet master and perform unauthorized actions.
Specifically, given a valid certificate and private key, an agent
could retrieve catalogs from the master that it is not authorized to
access or it could poison the puppet master's caches for any
puppet-generated data that supports caching such as catalogs, nodes,
facts, and resources. The extent and severity of this vulnerability
varies depending on the specific configuration of the master: for
example, whether it is using storeconfigs or not, which version,
whether it has access to the cache or not, etc.

A vulnerability has been found in Puppet that could allow a client
negotiating a connection to a master to downgrade the master's SSL
protocol to SSLv2. This protocol has been found to contain design
weaknesses. This issue only affects systems running older versions
(pre 1.0.0) of openSSL. Newer versions explicitly disable SSLv2.

A vulnerability found in Puppet could allow an authenticated client to
execute arbitrary code on a puppet master that is running in the
default configuration, or an agent with `puppet kick` enabled.
Specifically, a properly authenticated and connected puppet agent
could be made to construct an HTTP PUT request for an authorized
report that actually causes the execution of arbitrary code on the
master.

This vulnerability affects puppet masters 0.25.0 and above. By
default, auth.conf allows any authenticated node to submit a report
for any other node. This can cause issues with compliance. The
defaults in auth.conf have been changed."
