Although this type of stack buffer overflow is still common on some platforms and in some development communities, there are a variety of other types of buffer overflow, including Heap buffer overflow and Off-by-one Error among others.

Is buffer overflow still a problem?

Buffer overflows can be exploited by attackers to corrupt software. Despite being well-understood, buffer overflow attacks are still a major security problem that torment cyber-security teams.
