Memory Corruption and Safety: Delphi is claimed to be memory-safe but is similar to C++ in memory safety. It supports arbitrary untyped pointers and unsafe pointer arithmetic. Examples show how memory corruption can lead to vulnerabilities.

• Stack-Based Buffer Overflow: Tried writing a simple stack buffer overflow in Delphi. In debug mode, bounds-checking catches the overflow. In release mode, without bounds-checking, the code overwrites the return address. Tips include considering enabling "Runtime errors" flags in release mode. Some system library routines like System.FillChar etc. are dangerous.
• The Heap and Use After Free: Examples show heap-based vulnerabilities. In one example, a string's memory is freed and then reallocated, leading to information disclosure. In another, an object's memory is freed and then reused, resulting in a use-after-free vulnerability.
