Stack Based Attacks in Linux 

Stack overflows in linux: tools, methods, & vulnerabilities. by Bryce Meyer
"Stack based attacks" against 32bit and 64bit linux has become and arms race between "methods to exploit software missteps" vs "operating system and x64 methods to stop them".
Will cover:

• how holes get in,
• compiler switches,
• an intro to "return oriented programming",
• shellcode, and
• mitigation like "stack canaries".
