It was designed to rapidly scan large networks, but works fine against single hosts.\r\n\r\nSecurity Fix(es):\n\nNmap versions up to and including 7.99 contains a denial of service vulnerability that allows remote attackers to crash the application by sending a crafted packet containing a zero-length TCP option.
