SPSS (Statistical Package for the Social Sciences) is a computer application that provides statistical analysis of data. It allows for in-depth data access and preparation, analytical reporting, graphics and modelling. SamplePower is a stand-alone product designed to work seamlessly with SPSS. It allows researchers to compare the effects of different study parameters, such as sample size, using analytical tools before beginning the study.


IBM SPSS SamplePower 3.0 and earlier ship with an ActiveX control (c1sizer.ocx) that does not properly check the data size when handling the TabCaption buffer. A remote attacker could exploit this vulnerability to cause a heap buffer overflow that could allow arbitrary remote code execution.
