Recently I am learning about Linux Heap exploitation and I came across some really good Phrack papers and blogs which explained different type of attacks in varying conditions, I have included the link of these blogs and papers in the next section. I also came across an amazing GitHub project How2Heap by shellpish team, this project has the example exploit code for various heap exploitation technique of different versions of Glibc out there in public, which help me to get a better understanding of how those attacks played out. That project also included a script to build Glibc with any version of your choice and test the exploit on that version.
