GUI-based testing of boundary overflow vulnerability
MetadataShow full item record
Boundary overflows are caused by violation of constraints, mostly limiting the range of internal values of a program, and can be provoked by an intruder to gain control of or access to stored data. In order to countermeasure this well-known vulnerability issue, this paper focuses on input validation of graphical user interfaces (GUI). The approach proposed generates test cases for numerical inputs based on GUI specification through decision tables. If boundary overflow error(s) are detected, the source code will be analyzed to localize and correct the encountered error(s) automatically.
