SSL: IIS SSL Malformed Cipher DoS
This signature detects attempts to exploit a known vulnerability against Microsoft Internet Information Server (IIS) Private Communications Transport. IIS versions 4.0 through 6.0 are vulnerable. Attackers can send a malformed SSL request to a Microsoft IIS server, causing the service to crash or execute arbitrary code.
Extended Description
