US Cybersecurity: The Urgent Need for Memory Safety in Software Products

• crun

  30 2,787 9.3 C

  A fast and lightweight fully featured OCI runtime and C library for running containers

  

It's interesting that, in light of things like this, you still see large software companies adding support for new components written in non-memory safe languages (e.g. C)

As an example Red Hat OpenShift added support for crun(https://github.com/containers/crun) this year(https://cloud.redhat.com/blog/whats-new-in-red-hat-openshift...), which is written in C as an alternative to runc, which is written in Go(https://github.com/opencontainers/runc)...

• runc

  32 11,428 9.3 Go

  CLI tool for spawning and running containers according to the OCI specification

  How to exploit a double free vulnerability in 2021. Use After Free for Dummies

No. In order to exploit modern memory corruptions, you have to most often send a shitload of data with significant lengths to fill up memory strategically and/or rop gadget jump addresses. None of this looks like real payloads.

The analogy to firewalls is that you would specify the exact condition of the input for it to forward to the actual program. For example, if your endpoint receives json, you would validate the json and check each field value for valid range, ie min max number of characters and what those character values could be for each field. Just like a firewall limits who can talk to who in way.
