Vulnerability Details

This vulnerability allows remote attackers to execute arbitrary code on 
vulnerable installations of SAP NetWeaver Business Client. User interaction is 
required to exploit this vulnerability in that the target must visit a 
malicious page or open a malicious file.

The specific flaw exists within the Load and LoadTheme methods of the 
SapThemeRepository ActiveX control (sapwdpcd.dll) implemented by SAP NetWeaver 
Business Client. Due to a failure in bounds checking, a user-supplied parameter 
supplied to the vulnerable methods can overflow a stack buffer resulting in 
arbitrary code execution under the context of the user running the browser.

Vendor Response

SAP has issued an update to correct this vulnerability. More details can be
