In the past weeks, the pwn.college Dynamic Allocator Misuse module taught me many practical concepts I have long known from theory:

Use-after-free, double-free, tcache internals, LIFO reuse, tcache poisoning, arbitrary read, fake chunks, safe-linking, whitespace-armored addresses, and partial secret corruption.

Knowing theory is good, but experiencing those concepts in practice is priceless.
Thank you, @pwn.college!

Finished the pwn.college Yellow belt Dynamic Allocator Misuse - 4 weeks of type-2 fun.

Onward to greatness and my Yellow belt in pwn.college!
