Description Marcus Meissner 2015-03-30 12:27:23 UTC 
rh#1204855

The following commit fixed a denial of service in quassel:
https://github.com/quassel/quassel/commit/b5e38970ffd55e2dd9f706ce75af9a8d7730b1b8

It allows a connected client to cause a core crash by sending a CTCP
request which would be too long and multibyte.

This is mitigated by the fact that it requires an authed user.
