Weakness Name
Improper Resource Shutdown or Release
Description
The product does not release or incorrectly releases a resource before it is made available for re-use.
When a resource is created or allocated, the developer is responsible for properly releasing the resource as well as accounting for all potential paths of expiration or invalidation, such as a set period of time or revocation.
Common Consequences
Scope: Availability, Other
Impact: DoS: Resource Consumption (Other), Varies by Context
Notes: Most unreleased resource issues result in general software reliability problems, but if an attacker can intentionally trigger a resource leak, the attacker might be able to launch a denial of service attack by depleting the resource pool.
Scope: Confidentiality
Impact: Read Application Data
Notes: When a resource containing sensitive information is not correctly shutdown, it may expose the sensitive data in a subsequent allocation.
