The vulnerability is caused due to a design error in the Single Logical Screen daemon (SLSd) and can be exploited to create or overwrite arbitrary files with superuser privileges via a specially crafted packet sent to the daemon.

Successful exploitation allows execution of arbitrary code by e.g. overwriting .rhosts, cron scripts, or other files used for authentication.
