I am looking at some of the high security malloc implementations and omalloc and smalloc both look promising as an alternative to Google’s Malloc. But, instead of just taking my own opinion – what is the view of the community when it come… Continue reading Now that it is *almost* 2024, what are some of the most secure malloc implementations we have available?
I’m researching Buffer Overflow attacks, and while the web is full of various types of resources for Stack-Based Overflow attacks, the same can’t be said for Heap-Based ones.
Most articles I find only explain generally how the Heap works, … Continue reading Where to learn about Heap-Based Overflow Attacks under Linux?
I’m looking for a way to exploit CVE-2019-11500. Here’s how it’s described: In Dovecot before 2.2.36.4 and 2.3.x before 2.3.7.2 (and Pigeonhole before 0.5.7.2), protocol processing can fail for strings in quotes. This happens because the ‘… Continue reading Help creating an exploit for CVE-2019-11500
I tried to google this topic but most of them are conflicting each other. On the other side, I found a case where I can use either stack (local variable) or heap for a dynamic string. It’s C by the way. Any strong reference regarding this … Continue reading Stack vs Heap exploit, which have more CVE documented?
I’m learning about basic x86 overflows in C but normally I code with Python. Is there anyway that programs written in higher level languages can suffer from buffer/heap overflow?
Continue reading Do high level languages allow for buffer / heap overflow?

After compile the source code in a 64bits system, without any security mechanism I try to overflow the heap in order to overwrite the main return address on the s… Continue reading Heap overflow – strcpy() on x86_64 (64bit)
