PROGRAM EXECUTION DEVICE AND PROGRAM ANALYSIS DEVICE

摘要

Execute a countermeasure process for vulnerability reliably before an attack aiming at vulnerability occurs. A vulnerability countermeasure processing unit 1233 performs a countermeasure process for vulnerability of a vulnerable library function being a general-purpose library function that has vulnerability among the general-purpose library functions included in a general-purpose library 1230. A countermeasure selection unit 1232, when a call for the vulnerable library function is requested at execution of a Web application 1220, makes the vulnerability countermeasure processing unit 1233 perform the countermeasure process for the vulnerability of the vulnerable library function, and after the countermeasure process is performed by the vulnerability countermeasure processing unit 1233, calls the vulnerable library function.
