The official eggdrop Docker images before 1.8.4rc2 contain a blank password for a root user. Systems using the Eggdrop Docker container deployed by affected versions of the Docker image may allow an remote attacker to achieve root access with a blank password.

mod/server.mod/servmsg.c in Eggheads Eggdrop and Windrop 1.6.19 and earlier allows remote attackers to cause a denial of service (crash) via a crafted PRIVMSG that causes an empty string to trigger a negative string length copy. NOTE: this issue exists because of an incorrect fix for CVE-2007-2807.
