CVE-2017-8983

OpenRC opentmpfiles, hasta la versión 0.1.3, cuando el sysctl fs.protected_hardlinks está desactivado, permite que los usuarios locales se hagan dueños de archivos arbitrarios mediante la creación de un vínculo físico en un directorio en el que se ejecutará "chown -R".

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Hewlett Packard Enterprise Intelligent Management Center. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed.
The specific flaw exists within the handling of the parafile parameter provided to the redirectviewer servlet. When parsing this parameter, the process does not properly validate a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code under the context of SYSTEM.
