Fedora 10 Update: eggdrop-1.6.19-4.fc10
Posted by Benjamin D. Thomas   
Fedora 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.
