How to debug buffer corruptions - My STM32 case study
Memory corruptions !! The biggest nightmare for security engineers and hacker's jackpots for remote code execution, all of this starts with as simple as missing boundary checks combined with insane memory copy lengths. In this post let's deep dive into one of the similar issues I faced while porting nRF8001 BLE library onto STM32L151 MCU and in the process let us also gain some knowledge here and there about techniques & tools used to debug this kind of issues. Step 1 - Identify What is the p
