callbacks should only be executed once for every system service call The IA-32 architecture does not support execute only pages but treats the readable state of a page as identical to the executable state When a process is created a single 4kb page is allocated for its handle table, which can hold up to 256 handles, and more memory is assigned to it only if needed Thus, every push copies the data to that address and advances the stack pointer by the amount of data that was pushed ion sourceDifferent approaches exist on performing this observations illustrates this To this end the corresponding taint sensitive sink is implemented in the function that is executed whenever memory writes occur plasmatronThis knowledge is then tested against the policy and it is decided whether the application is malicious or benign In this mode all virtual disk images are used in a read only fashion and sectors that are written are stored in temporary files For this example we produced two binaries An object body that can have any size, content and structure its author likes and the object header that directly precedes the object body ion sourceStatic analysis gathers information about the program by investigating its source code or its binary representation
