Stack-based buffer overflow in mod/server.mod/servrmsg.c in Eggdrop 1.6.18, and possibly earlier, allows user-assisted, remote IRC servers to execute arbitrary code via a long private message.
Share.mod in Eggheads Eggdrop IRC bot 1.6.10 through 1.6.15 can mistakenly assign STAT_OFFERED status to a bot that is not a sharebot, which allows remote attackers to use STAT_OFFERED to promote a bot to a sharebot and conduct unauthorized activities.
