What is CVE-2014-9403?
The CWebAdminMod::ChanPage function in ZNC versions prior to 1.4 is susceptible to a denial of service attack. Remote authenticated users can exploit this vulnerability by creating a channel that has the same name as an existing channel, albeit without the leading # character. This action can lead to a NULL pointer dereference, resulting in a system crash. The issue stems from a 'use-after-delete' error, emphasizing the need for proper validation in channel naming to safeguard system stability.
