Stack-based buffer overflow in EAI WebViewer3D ActiveX control (webviewer3d.dll) in SAP AG SAPgui before 7.10 Patch Level 9 allows remote attackers to execute arbitrary code via a long argument to the SaveViewToSessionFile method.
SAP GUI (Sapgui) 4.6D allows remote attackers to cause a denial of service (crash) via a connection to a high-numbered port, which generates an "unknown connection data" error.
The default installation of SAP R/3 46C/D allows remote attackers to bypass account locking by using the RFC API instead of the SAPGUI to conduct a brute force password guessing attack, which does not lock out the account like the SAPGUI does.
