From $url: If we receive multiple CTCP requests in one PRIVMSG we now answer with one packed NOTICE containing all CTCP replies. This fixes a possible DoS Attack rendering Quassels IRC connection useless. Upgrading is strongly recommended. Thanks to Jima for reporting and supporting. Fixed software is already in the tree, and vulnerable code has already been removed. This bug is for GLSA tracking only.
GLSA Vote: Yes, unassisted remote DoS.
YES too, request filed.
Ping.
