Uncontrolled Resource Consumption
Microsoft Exchange 2000, when used with Microsoft Remote Procedure Call (MSRPC), allows remote attackers to cause a denial of service (crash or memory consumption) via malformed MSRPC calls.
CWE-400 - Uncontrolled resource consumption
An uncontrolled resource allocation attack (also known as resource exhaustion attack) triggers unauthorized overconsumption of the limited resources in an application, such as memory, file system storage, database connection pool entries, and CPU. This may lead to denial of service for valid users and degradation of the application's functionality as well as that of the host operating system.
