Description Vincent Danen 2013-05-29 20:42:43 UTC

Multiple vulnerabilities were reported in ZNC which can be exploited by malicious authenticated users to cause a denial of service.  These flaws are due to errors when handling the "editnetwork", "editchan", "addchan", and "delchan" page requests; they can be exploited to cause a NULL pointer dereference.  These flaws only affect version 1.0.

These issues have been fixed in git [1].
