SAP DB Web Server WAHTTP.EXE Multiple Buffer Overflow Vulnerabilities

SAP DB Web Server is prone to multiple buffer-overflow vulnerabilities because it fails to adequately bounds-check user-supplied input before copying it to an insufficiently sized buffer.

Successfully exploiting these issues will allow an attacker to execute arbitrary code with SYSTEM-level privileges. Failed exploit attempts will result in a denial-of-service condition.
