Stack buffer overflow is a type of the more general programming malfunction known as buffer overflow (or buffer overrun). Overfilling a buffer on the stack is more likely to derail program execution than overfilling a buffer on the heap because the stack contains the return addresses for all active function calls. [1] Stack buffer overflow can ...
Visualization of a software buffer overflow. Data is written into A, but is too large to fit within A, so it overflows into B.. In programming and information security, a buffer overflow or buffer overrun is an anomaly whereby a program writes data to a buffer beyond the buffer's allocated memory, overwriting adjacent memory locations.
Buffer overflow – out-of-bound writes can corrupt the content of adjacent objects, or internal data (like bookkeeping information for the heap) or return addresses. Buffer over-read – out-of-bound reads can reveal sensitive data or help attackers bypass address space layout randomization .
A code sanitizer is a programming tool that detects bugs in the form of undefined or suspicious behavior by a compiler inserting instrumentation code at runtime. The class of tools was first introduced by Google's AddressSanitizer (or ASan) of 2012, which uses directly mapped shadow memory to detect memory corruption such as buffer overflows or accesses to a dangling pointer (use-after-free).
This helps to prevent certain buffer overflow exploits from succeeding, particularly those that inject and execute code, such as the Sasser and Blaster worms. These attacks rely on some part of memory, usually the stack, being both writable and executable; if it is not, the attack fails.

[1] Overfilling a buffer on the stack is more likely to derail program execution than overfilling a buffer on the heap because the stack contains the return addresses for all active function calls.
These are references to patterns that can support, relate to or mitigate the attack and the listing for the related pattern should note that. An example of related patterns for an Integer Overflow Attack Pattern is: Mitigation Patterns – Filtered Input Pattern, Self Defending Properties pattern Related Patterns – Buffer Overflow Pattern
Deep Packet Inspection is able to detect a few kinds of buffer overflow attacks. DPI may be used by enterprise for Data Leak Prevention (DLP). When an e-mail user tries to send a protected file, the user may be given information on how to get the proper clearance to send the file. [12] [example needed] [clarification needed]
