Abstract
Several techniques exist to dynamically detect heap and stack corruption and are well known in the industry. Examples of such tools are Valgrind and eFence. Other tools like AddressSanitizer (ASan) rely on the compiler to add instrumentation to the code to detect memory corruption. In this presentation a clever approach based on MMUs and virtual memory is introduced. This method can easily detect some out-of-bound access to the stack or heap and latent access to previously released memory.

Audience
Anyone interested in memory corruption detection techniques
