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 attack
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. In 2014 a threat known as ‘heartbleed’ exposed hundreds of millions of users to attack because of a bu...
Buffer overflow refers to a common cybersecurity vulnerability that happens when a program or process writes more data into a buffer than it can handle. In other words, too much data passes into memory that doesn't have enough space. Then, the extra data ends up overflowing into adjacent me...
Prevention of Buffer flow Vulnerability in Cyber Security using Stamp Free Analysis TechniquesStamp-free out-of-the-box has an application-layer for jamming the buffer overflow attack messages targeting at various Internet services. Focus on buffer overflow attacks whose payloads contain executable code...
What is Buffer Overflow Attack in cyber security Buffer Overflow Attacksoccur as a result of excess data being input into a system memory buffer. Moreover, when the memory buffer’s capacity has been reached, the music will stop playing. To avoid overwriting other data in your computer’s mem...

Figure 1: Simple example of buffer overflow where data is corrupted In the simplified example above a buffer is intended to have size 8 and is adjacent to a data area. If the buffer overflows to a data area, then it is likely that any program using that data may behave in an anomalous...
QuickStudy: A buffer overflow occurs when a computer program attempts to stuff more data into a buffer (a defined temporary storage area) than it can hold. The excess data bits then overwrite valid data and can even be interpreted as program code and exe
This error occurs when there is more data in a buffer than it can handle, causing data to overflow into adjacent storage. This vulnerability can cause a system crash or, worse, create an entry point for a cyberattack. C and C++ are more susceptible to buffer overflow. ...
buffer overflow (programming) What happens when you try to store more data in a buffer than it can handle. This may be due to a mismatch in the processing rates of the producing and consuming processes (see overrun and firehose syndrome), or because the buffer is simply too small to hold...
