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.
