I. Description

SAP DB is a database server that includes a series of web-based configuration tools.

A stack based buffer overlfow exists in the SAP DB web server (WAHTTP.exe). Note that this vulnerability only affects the web server that is included with the SAP DB server. Systems hosting the SAP web tools on a different web server are not affected by this vulnerability.
