In Mitre's CVE dictionary: CVE-2013-4761, CVE-2013-4956.
More information:

Several vulnerabilities were discovered in puppet, a centralized configuration management system. The Common Vulnerabilities and Exposures project identifies the following problems:

  • CVE-2013-4761

    The resource_type service (disabled by default) could be used to make puppet load arbitrary Ruby code from puppet master's file system.

  • CVE-2013-4956

    Modules installed with the Puppet Module Tool might be installed with weak permissions, possibly allowing local users to read or modify them.

The stable distribution (wheezy) has been updated to version 2.7.33 of puppet. This version includes the patches for all the previous DSAs related to puppet in wheezy. In this version, the puppet report format is now correctly reported as version 3.

It is to be expected that future DSAs for puppet update to a newer, bug fix-only, release of the 2.7 branch.

The oldstable distribution (squeeze) has not been updated for this advisory: as of this time there is no fix for CVE-2013-4761 and the package is not affected by CVE-2013-4956.

For the stable distribution (wheezy), these problems have been fixed in version 2.7.23-1~deb7u1.

For the testing distribution (jessie) and the unstable distribution (sid), these problems have been fixed in version 3.2.4-1.

We recommend that you upgrade your puppet packages.
