摘要：PROBLEM TO BE SOLVED: To provide an information processing device capable of preventing an illegal program from being executed even when the illegal program is embedded in content data containing algorithm for dynamic memory allocation described in a script language, an illegal program execution prevention method, and a program and a recording medium.SOLUTION: An information processing device comprises: a hook unit 321 which hooks issuance of an instruction for executing algorithm for dynamic memory allocation included in browsed digital content data; an inspection unit 322 which inspects contents in a region of the address secured by the immediately preceding execution of algorithm for dynamic memory allocation at every hook; and a processing unit 325 which terminates processing for the browsed digital content data, when only an amount of data enough to determine that omission codes were sprayed exists in the region of the address as a result of the inspection.SELECTED DRAWING: Figure 5
