Micro-Learning Topic: Buffer overflow (Detected by phrase)

Matched on "Buffer Overflow"

What is this? (2min video)

A 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.

Micro-Learning Topic: Stack overflow (Detected by phrase)

Matched on "Stack-based Buffer Overflow"

What is this? (2min video)

Also referred to as Stack buffer overflows. This vulnerability occurs when data received by a program is written to a memory location on the stack and the allocated space is not large enough to take the whole input. If proper boundary checks are not implemented, or unsafe functions like sprintf, fgets etc. are used which don't require a destination size limit the stack memory after the target buffer may be written to, allowing an attacker to alter the normal behaviour of the program. Most modern compilers now have a secure switch which may reorder stack variables and generate extra code to protect against this type of vulnerability.
