Description Florian Weimer 2015-08-21 10:31:55 EDT
It was discovered that local users could use the criu daemon to create
arbitrary files and take ownership of existing files, due to the
creation of log and dump files in a user-supplied directory path.
This allows unprivileged local users to gain root privileges.


This issue was discovered by Florian Weimer of Red Hat Product Security.
