Description

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. The current remote denial of service is tracked as CVE-2009-1789.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
