puskuriylivuoto

Puskuriylivuoto, often translated as buffer overflow, is a software vulnerability that occurs when a program attempts to write data beyond the allocated memory buffer. This can happen if the input data is larger than the buffer designed to hold it. When this happens, the excess data spills over into adjacent memory locations.

The consequences of a buffer overflow can range from minor program malfunctions, such as crashes, to significant security risks. Malicious actors can exploit buffer overflows to overwrite critical data in memory, potentially injecting their own code or manipulating the program's execution flow. This can lead to unauthorized access, data theft, or even complete system compromise.

Common causes of buffer overflows include improper input validation, where the program doesn't check the size of incoming data before storing it. Programming languages that lack automatic bounds checking on memory operations are also more susceptible. Developers often use specific techniques and secure coding practices to prevent buffer overflows, such as using functions that perform bounds checking or employing memory-safe languages. Understanding and mitigating buffer overflows is a crucial aspect of software security.
