Description Huzaifa S. Sidhpurwala 2014-12-29 07:56:38 UTC 
When a znc web administrator tried to add a channel, which already existed, via web admin interface, it would cause a crash if the channel name isn't prefixed with '#' (i.e you already have a channel '#potato' but you try to add 'potato' without the '#' prefix). 

This only appears to happen if the channel is already in the list and not if you are adding a new channel that isn't already in the list.

Comment 1 Huzaifa S. Sidhpurwala 2014-12-29 08:02:50 UTC 
This security flaw has already been addressed in Fedora and EPEL via the following security advisories:

https://admin.fedoraproject.org/updates/FEDORA-2014-5214/znc-1.2-3.fc19
https://admin.fedoraproject.org/updates/FEDORA-2014-5254/znc-1.2-3.fc20
https://admin.fedoraproject.org/updates/FEDORA-EPEL-2014-1137/znc-1.2-3.el6
https://admin.fedoraproject.org/updates/FEDORA-EPEL-2014-1119/znc-1.2-3.el5

Currently Fedora-19, Fedora-20, EPEL-5, EPEL-6 and EPEL-7 contain znc-1.4, which also contains a fix for this issue.
