The 'malloc' function in C programming is used to dynamically allocate memory on the heap, returning a pointer to the beginning of the allocated space. It is crucial to manage this memory properly, as failure to free it using 'free' can lead to memory leaks, while improper access can cause undefined behavior.

In programming, a 'free function' refers to a function that is not bound to a class or object and exists independently in the global scope. This concept is often used to create utility functions that can operate across different data types or objects, enhancing code modularity and reusability.

Memory leaks occur when a computer program incorrectly manages memory allocations, leading to a situation where memory that is no longer needed is not released. This can cause a program to consume increasing amounts of memory, potentially degrading system performance or causing the program to crash.

Undefined behavior in programming occurs when the code executes in a way that is not predictable or specified by the language standard, often leading to unpredictable results or system crashes. It is a critical concept in programming languages like C and C++, where certain operations can lead to undefined behavior if not handled correctly, making it essential for developers to understand and avoid these pitfalls to ensure program stability and security.
