Grr. We too have a remote crash bug. No, not a buffer overflow, we don’t have them ;) And not the %s bug, but just some special case. It’s not possible to make it run any arbitrary code, it can only crash irssi. This affects all 0.7.9x versions. You can get the patch here: </files/crashfix.patch> or get the whole 0.7.95-3 tarball. Updated .debs and .rpms would be nice to have soon :) UPDATE: .deb is now updated (version 0.7.95-2).
