Detailsinfo

A vulnerability classified as problematic has been found in Puppetlabs Puppet Enterprise Users up to 2.0.1 (Service Management Software). This affects the function Puppet::FileBucket::File of the component Filesystem. The manipulation with an unknown input leads to a memory allocation vulnerability. CWE is classifying the issue as CWE-789.
