A buffer overflow occurs when data written to a buffer exceeds the length of the buffer, so that corrupting data values in memory addresses adjacent the end of the buffer. This often occurs when copying data into a buffer without sufficient bounds checking. You can refer to Aleph One’s famo...

In a classic exploit of buffer overflow, data is stored in undersized stack buffer that is sent by the attacker in the first place. As a result, the function's return pointer and all the other information on the call stack is overwritten. The transfer of control to malicious code being ...
bounds functionality checking to protect the buffer. Avoid using functions that do not check the buffer (for example, in the C language, replace gets() with fgets()). Use built-in protected languages or use special security programs in the language code to prevent buffer overflow vulnerabilities...
Heap buffer overflow in Mojom IDL in Google Chrome prior to 116.0.5845.96 allowed a remote attacker who had compromised the renderer process and gained control of a WebUI process to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: Medium) ...
A buffer overflow, or buffer overrun, is a common Key Concepts of Buffer Overflow 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 ...
If they match, the program continues; otherwise, it terminates the process instantaneously. The proposed approach, Secure Patrol, is efficient, secure against stack-based buffer overflow and resistant to GOT manipulation.Information Systems SecurityJaydeep SolankiAenik ShahManik Lal Das...
When a file system driver gets this type of query it fills in as much information as fits in the caller’s buffer and, if the buffer is too small to hold the entire structure, returns a buffer overflow error and the size of the buffer required to hold all the data. I suspect that ...
Certain HP Enterprise LaserJet, and HP LaserJet Managed Printers are potentially vulnerable to buffer overflow when using libwebp in Google Chrome or other web browsers. This issue occurs in all versions of libwebp prior to 1.3.2.
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...
