This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of IBM SPSS. 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 SetLicenseInfoEx() method exposed by the mraboutb.dll ActiveX Control. String data supplied to the first parameter (strInstallDir) of SetLicenseInfoEx() is copied into a 256 byte global buffer without first checking the string length. This overflow can be exploited to remotely execute arbitrary code on the target system.
