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 is a software coding error that enables hackers to exploit vulnerabilities, steal data, and gain unauthorized access to corporate systems. Discover what is a buffer overflow attack and how Fortinet can mitigate and prevent overflow attacks.

Buffer overflow is probably the best known form of software security vulnerability. Most software developers know what a buffer overflow vulnerability is, but buffer overflow attacks against both legacy and newly-developed applications are still quite common.

2025年1月29日 · Buffer overflow vulnerabilities occur when a program allows more data to be written to a buffer than it can hold, potentially leading to data corruption, security breaches, and exploitation by attackers.

What is buffer overflow? Buffer overflow is an anomaly that occurs when software writing data to a buffer overflows the buffer’s capacity, resulting in adjacent memory locations being overwritten.

2024年9月11日 · Buffer overflows occur when a program writes more data to a buffer than it can hold. This excess data spills over into adjacent memory, potentially overwriting critical information. Programming errors, such as failing to check input sizes or incorrect memory allocation, can cause buffer overflows.

2024年11月7日 · A buffer overflow (or buffer overrun) occurs when the volume of data exceeds the storage capacity of the memory buffer. As a result, the program attempting to write the data to the buffer overwrites adjacent memory locations.

Buffer overflow occurs when data exceeds the buffer's storage capacity, leading to data spilling over into adjacent memory spaces. This overflow can corrupt data, crash the program, or lead to the execution of malicious code if an attacker exploits the situation.

2025年1月11日 · In the world of cybersecurity, a buffer overflow is a critical vulnerability that occurs when a program writes more data to a buffer than it can hold. This leads to data overwriting adjacent memory locations, potentially exposing the system to malicious attacks.

2024年3月31日 · As the name implies, a buffer overflow is a type of vulnerability that deals with buffers, or memory allocations in languages that offer direct, low-level access to read and write memory. In the simplest terms, it is when a buffer's storage capacity is exceeded by a to-large quantity of data.
