kernel: mISDN issue
Last modified: 2010-11-22 00:15:09 EST
Description of problem:
This issue was first reported here:
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):
ok, only useful information. nothing to hide.
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.

No progress so far.
