Description Adam Mariš 2015-08-12 05:43:16 EDT

It was reported that pcs package is vulnerable to command injection with root privileges.
A user supplied string is used to in running a system command. If the user
uses escape characters they can run a command as the root user on the system.

To do this the user must already have access to login to pcsd (Be a member of
the hacluster group).
