## Description

SAP NetWeaver Application Server (SAP Message Server) does not properly size memory allocations when handling certain HTTP requests. An unauthenticated attacker could send a specially crafted request to trigger a heap buffer overflow in affected functionality. Successful exploitation causes the component to abort and remain unavailable until it is restarted by the framework, resulting in a high impact on availability of the system. There is no impact on confidentiality and integrity of the application.
