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.
