• Use of uninitialised memory
• Reading/writing memory after it has been free’d
• Reading/writing off the end of malloc’d blocks
• Reading/writing inappropriate areas on the stack
• Memory leaks -- where pointers to malloc’d blocks are lost forever
• Mismatched use of malloc/new/new [] vs free/delete/delete []
• Overlapping src and dst pointers in memcpy() and related functions
