Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to unsafe handling of temporary files and directories. Before the insights-client has been registered on the system by root, an unprivileged local user can create the /var/tmp/insights-client directory. After the client is registered by root, the local user can execute arbitrary files with root privileges from the affected directory.

Install updates from vendor's website.
