Vulnerability CVE-2007-4407
Published: 2007-08-18   Modified: 2012-02-12

Description:
ircu 2.10.12.03 and 2.10.12.04 does not associate a timestamp with ops privilege on an unused channel (zannel), which allows remote attackers to (1) set or remove certain channel modes via a "netriding" attack or (2) take over a channel by joining an unlinked server with the A/Upass and then setting a new Apass.
