-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Critical: ruby193-puppet security update Advisory ID: RHSA-2013:1284-01 Product: Red Hat OpenStack Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-1284.html Issue date: 2013-09-24 CVE Names: CVE-2013-3567 CVE-2013-4761 CVE-2013-4956 ===================================================================== 1. Summary: Updated ruby193-puppet packages that fix three security issues are now available for Red Hat OpenStack 3.0. The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: OpenStack 3 - noarch 3. Description: Puppet allows provisioning, patching, and configuration of clients to be managed and automated. A flaw was found in the way Puppet handled YAML content during Representational State Transfer (REST) API calls. An attacker could construct a request containing a crafted YAML payload that would cause the Puppet master to execute arbitrary code. (CVE-2013-3567) It was found that resource_type requests could be used to cause the Puppet master to load and run Ruby files from anywhere on the file system. In non-default configurations, a local user on the Puppet master server could use this flaw to have arbitrary Ruby code executed with the privileges of the Puppet master. (CVE-2013-4761) It was found that Puppet Module Tool (that is, running "puppet module" commands from the command line) applied incorrect permissions to installed modules. If a malicious, local user had write access to the Puppet module directory, they could use this flaw to modify the modules and therefore execute arbitrary code with the privileges of the Puppet master. (CVE-2013-4956) Red Hat would like to thank Puppet Labs for reporting these issues. Upstream acknowledges Ben Murphy as the original reporter of CVE-2013-3567. These ruby193-puppet packages are used by Foreman, which provides facilities for rapidly deploying Red Hat OpenStack 3.0. In this use case, Puppet master is used and exposed to these issues. Note that Foreman is provided as a Technology Preview. For more information on the scope and nature of support for items marked as Technology Preview, refer to https://access.redhat.com/support/offerings/techpreview/ Users of Red Hat OpenStack 3.0 are advised to upgrade to these updated packages, which correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 5.
