Security of memory allocators for C and CPP
I will discuss a variety of memory allocators that are available for C and C++ and how they can be exploited.Afterwards I will describe our modification to one of these memory allocators that makes it more resilient to attacks.The talk will cover security issues with a range of memory allocators:- dlmalloc (linux malloc)- csri/quickfit- phkmalloc (bsd malloc)- Boehm's garbage collector- Windows mallocOur talk will describe how an attacker would attack the memory management of such memory allocators. The talk will also detail our own modification to dlmalloc to make it more secure against code injection attacks.
