A program copies more data into a fixed-size memory area than it can hold, overwriting adjacent memory and allowing an attacker to run injected instructions. This weakness is known as a:

This weakness is a buffer overflow. The program writes more data into a fixed-size memory area than it can hold, spilling into adjacent memory, which an attacker can use to inject and execute malicious instructions. Bounds checking in code is the usual remedy.

Explanation

Writing beyond the bounds of a fixed memory buffer and overwriting neighbouring memory is a buffer overflow. A race condition concerns timing of concurrent operations rather than memory bounds.
