EFnet Paralyzed By Vulnerability 156

An anonymous reader writes "EFnet member Fionn 'Fudge' Kelleher reported several vulnerabilities in the IRC daemons charybdis, ircd-ratbox, and other derivative IRCds. The vulnerability was subsequently used to bring down large portions of the EFnet IRC network." By crafting a particular message, you can cause the IRC daemon to call strlen(NULL) and game over, core dumped.
