![]() 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. Descriptionīuffer overflow is probably the best known form of software security vulnerability. NVD CategorizationĬWE-788: Access of Memory Location After End of Buffer: This typically occurs when a pointer or its index is incremented to a position after the buffer or when pointer arithmetic results in a position after the buffer. Writing outside the bounds of a block of allocated memory can corrupt data, crash the program, or cause the execution of malicious code. In this case, a buffer is a sequential section of memory allocated to contain anything from a character string to an array of integers. See the OWASP Testing Guide article on how toĪ buffer overflow condition exists when a program attempts to put more data in a buffer than it can hold or when a program attempts to put data in a memory area past a buffer.
