Incorrect array processing may lead to various security problems, for example:

Buffer overflow: If the program does not check the length of an array before writing data to it, an attacker can inject more data than the allocated buffer allows. This can cause adjacent memory areas to be overwritten, allowing the attacker to execute arbitrary code or change the state of the program.
Array overruns: If the code does not include checks for array overruns when accessing array elements, an error may be introduced allowing an attacker to access memory or change variable values, which can cause the program to malfunction or perform unwanted actions.
Read/write errors: Uncontrolled access to an array may lead to read/write errors. It is leads to information leaks or data changes that may affect the correct operation of the program.
