Descriptions

Puppet Module Tool (PMT), as used in Puppet 2.7.x before 2.7.23 and 3.2.x before 3.2.4, and Puppet Enterprise 2.8.x before 2.8.3 and 3.0.x before 3.0.1, installs modules with weak permissions if those permissions were used when the modules were originally built, which might allow local users to read or modify those modules depending on the original permissions.

Puppet Module Tool (PMT), usado en Puppet 2.7.x anterior a 2.7.23 y 3.2.x anterior a 3.2.4, y Puppet Enterprise 2.8.x anterior a 2.8.3 y 3.0.x anterior a 3.0.1, instala módulos con permisos débiles si estos son utilizados cuando los módulos se construyen inicialmente, lo que podría permitir a usuarios locales leer o modificar dichos módulos dependiendo de los permisos originales.

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 API calls. An attacker could construct a request containing a crafted YAML payload that would cause the Puppet master to execute arbitrary code. 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.
