In certain computer security attacks, an outside party compromises one computer application (such as a web browser) and then uses that application to submit a ‘system call’ to the operating system, effectively asking the operating system to perform a specific function. However, instead of a routine function, the attacker uses the system call to attempt to gain control of the operating system.
