start_kdeinit is a wrapper to launch kdeinit with a lower OOM
score on Linux. This helper is used to ensure that a
single KDE application triggering the Linux kernel OOM killer
does not kill the whole KDE session. By default,
start_kdeinit is installed as setuid root. The start_kdeinit
processing of user-influenceable input is faulty.
If start_kdeinit is installed as setuid root, a local user
might be able to send unix signals to other processes, cause
a denial of service or even possibly execute arbitrary code.
