Software Description: - - puppet: Centralized configuration management Details: It was discovered that Puppet did not drop privileges when executing commands as different users. If an attacker had control of the execution manifests or the executed command, this could be used to execute code with elevated group permissions (typically root). (CVE-2012-1053) It was discovered that Puppet unsafely opened files when the k5login type is used to manage files. A local attacker could exploit this to overwrite arbitrary files and escalate privileges. (CVE-2012-1054) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: puppet-common 2.7.1-1ubuntu3.5 Ubuntu 11.04: puppet-common 2.6.4-2ubuntu2.8 Ubuntu 10.10: puppet-common 2.6.1-0ubuntu2.6 Ubuntu 10.04 LTS: puppet-common 0.25.4-2ubuntu6.6 In general, a standard system update will make all the necessary changes.
