Jigsaw DOS device request denial of service
|jigsaw-dos-device-dos (9587)||Medium Risk|
Jigsaw is vulnerable to a denial of service attack caused by improper handling of requests for DOS device names. If a remote attacker sends multiple requests for a DOS device, the attacker could cause the Web server to consume all available server resources. The server must be restarted to regain normal functionality.
