SAP-DB/MaxDB WebDBM Remote Buffer Overflow Vulnerability

SAP-DB and MaxDB are prone to a remote buffer-overflow vulnerability because these applications fail to perform sufficient bounds-checking of user-supplied data before copying it to an insufficiently sized memory buffer.

This issue may allow remote attackers to execute arbitrary machine code with privileges of the 'wahttp' process. Failed exploit attempts will likely crash the application, denying further service to legitimate users.
