As alluded to in http://www.mediawiki.org/wiki/Manual:IRC_RC_Bot, it is possible for anyone to inject fake RC messages into the Wikimedia RC feeds on IRC. This can be used to mess up bots that rely on these feeds, in particular anti-vandalism bots.
You have tested this?
That page also says that this possibility can be eliminated through the use of iptables. If a sysadmin can confirm this, the bug is WORKSFORME.
Should be fixed now. Will update the documentation on wikitech to avoid having this happen again.
Yes, the recent iptable changes closed the UDP port to outside access.
Closing old verified bugs.
