## Description

znc.cpp in ZNC before 0.092 allows remote authenticated users to cause a
denial of service (crash) by requesting traffic statistics when there is an
active unauthenticated connection, which triggers a NULL pointer
dereference, as demonstrated using (1) a traffic link in the web
administration pages or (2) the traffic command in the /znc shell.

### [sbeattie](https://launchpad.net/~sbeattie)

debian's CVE tracker for some reason references gitolite with
this CVE; I think it's an editing mistake.
