From Patrick Koppen isdn4linux at koppen.de on Sun Dec 13 18:17:31 CET 2009,

"I tried misdn 1.1.21 as a normal user (NOT ROOT):

 $ ./tools/misdn_info

ok, only useful information. nothing to hide.

 $ ./tools/misdn_log

every user can see every call, could be some privacy issue.

 $ ./tools/misdn_rename 0 test

little DoS, lcr will not find a named port...

 $ ./example/testcon -n 09009......

very expensive.... this should NOT work!

I suggest to restrict access to the data socket. The base socket ioctl IMSETDEVNAME should be protected too."

The thread mentioned in comment #0 died out. I'm checking with Patrick and SuSE folks to see if there's any follow-ups since then.
