SAP's MaxDB is "a database software product. MaxDB was released as open source from version 7.5 up to version 7.6.00. Later versions are no longer open source but are available for download from the SAP SDN website (sdn.sap.com) as a community edition with free community support for public use beyond the scope of SAP applications. The "vserver" program is responsible for accepting and handling communication with remote database clients". Remote exploitation of a signedness error in the "vserver" component of SAP AG's MaxDB could allow attackers to execute arbitrary code.
