Description Agostino Sarubbo gentoo-dev 2013-05-29 18:57:35 UTC
From ${URL} :

Multiple vulnerabilities have been reported in ZNC, which can be 
exploited by malicious users to cause a DoS (Denial of Service).

The vulnerabilities are caused due to errors when handling the 
"editnetwork", "editchan", "addchan", and "delchan" page requests and 
can be exploited to cause a NULL pointer dereference.

The vulnerabilities are reported in version 1.0.

Fixed in the git repository.
